You can add the following code anywhere that you want.

/**
* Eav Entity Attribute Collection
*
* @var \Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection
*/
protected $_entityAttributeCollection;
 
/**
* @var \Magento\Eav\Model\Entity\Attribute
*/ 
protected $_entityAttribute;
 
/**
* @var \Magento\Eav\Model\ResourceModel\Entity\Attribute\Option\Collection
*/ 
protected $_attributeOptionCollection;
    
/**
* @param \Magento\Backend\Block\Template\Context $context
* @param \Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection $eavEntityAttributeCollection
* @param array $data
*/
public function __construct(
    \Magento\Backend\Block\Template\Context $context,
    \Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection $entityAttributeCollection,
    \Magento\Eav\Model\Entity\Attribute $entityAttribute,
    \Magento\Eav\Model\ResourceModel\Entity\Attribute\Option\Collection $attributeOptionCollection,
    array $data = []
) {
    $this->_entityAttributeCollection = $entityAttributeCollection; 
    $this->_entityAttribute = $entityAttribute;
    $this->_attributeOptionCollection = $attributeOptionCollection;
 
    parent::__construct($context, $data);
}
 
/**
* Load attribute data by code
*
* @param   mixed $entityType    Can be integer, string, or instance of class Mage\Eav\Model\Entity\Type
* @param   string $attributeCode
* @return  \Magento\Eav\Model\Entity\Attribute
*/
public function getAttributeInfo($entityType, $attributeCode)
{
    return $this->_entityAttribute
                ->loadByCode($entityType, $attributeCode);
}
 
/**
* Get all options of an attribute
*
* @param   int $attributeId
* @return  \Magento\Eav\Model\ResourceModel\Entity\Attribute\Option\Collection
*/
public function getAttributeOptionAll($attributeId)
{
    return $this->_attributeOptionCollection
                ->setPositionOrder('asc')
                ->setAttributeFilter($attributeId)
                ->setStoreFilter()
                ->load();
}
 
/**
* Get attribute option data of a single option of the attribute
*
* @param   int $attributeId
* @param   int $optionId
* @return  \Magento\Eav\Model\ResourceModel\Entity\Attribute\Option\Collection
*/
public function getAttributeOptionSingle($attributeId, $optionId)
{
    return $this->_attributeOptionCollection
                ->setPositionOrder('asc')
                ->setAttributeFilter($attributeId)
                ->setIdFilter($optionId)
                ->setStoreFilter()
                ->load()
                ->getFirstItem();
}
 
/**
* Get attributes by code
* Multiple entity types can have same attribute code
* Entity types 'catalog_product' & 'catalog_category' both have 'name' attribute code
* So, this function can return object of size greater than 1
*
* @return Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection
*/ 
public function getAttributesByCode($code) {
    $this->_entityAttributeCollection->getSelect()->join(
                ['eav_entity_type'=>$this->_entityAttributeCollection->getTable('eav_entity_type')],
                'main_table.entity_type_id = eav_entity_type.entity_type_id',
                ['entity_type_code'=>'eav_entity_type.entity_type_code']);                
    
    $attributes = $this->_entityAttributeCollection->setCodeFilter($code);
    
    return $attributes;
}
 
/**
* Get single product attribute data 
*
* @return Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection
*/
public function getProductAttributeByCode($code) {
    $this->_entityAttributeCollection->getSelect()->join(
                ['eav_entity_type'=>$this->_entityAttributeCollection->getTable('eav_entity_type')],
                'main_table.entity_type_id = eav_entity_type.entity_type_id',
                ['entity_type_code'=>'eav_entity_type.entity_type_code']);                
    
    $attribute = $this->_entityAttributeCollection
                      ->setCodeFilter($code)
                      ->addFieldToFilter('entity_type_code', 'catalog_product')
                      ->getFirstItem();
    
    return $attribute;
}

For example, here, we will fetch the attribute data for the attribute “manufacturer” of “product”.

$attributeCode = ‘manufacturer’;
$entityType = 'catalog_product';
 
$attributeInfo = $block->getAttributeInfo($entityType, $attributeCode);
//var_dump($attributeInfo->getData());
 
$attributeId = $attributeInfo->getAttributeId();
$optionId = 49; // YOUR_OPTION_ID
 
$attributeOptionAll = $block->getAttributeOptionAll($attributeId);
//var_dump($attributeOptionAll->getData());
 
$attributeOptionSingle = $block->getAttributeOptionSingle($attributeId, $optionId);
//var_dump($attributeOptionSingle->getData());
