Create attribute option using Data patch in Magento2

Question

I am creating a product attribute with option using Magento 2.3 Data patch.

Used below code.

<?php
declare(strict_types=1);

namespace Vendor\Module\Setup\Patch\Data;

use Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface;
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\Patch\DataPatchInterface;

class AddFeatureAttribute implements DataPatchInterface
{

private $moduleDataSetup;
private $eavSetupFactory;
public $_storeManager;
private $logger;
protected $_dir;
public function __construct(
    ModuleDataSetupInterface $moduleDataSetup,
    EavSetupFactory $eavSetupFactory,
    \Psr\Log\LoggerInterface $logger,
    \Magento\Store\Model\StoreManagerInterface $storeManager,
    \Magento\Framework\Filesystem\DirectoryList $dir
) {
    $this->moduleDataSetup = $moduleDataSetup;
    $this->eavSetupFactory = $eavSetupFactory;
    $this->_storeManager = $storeManager;
    $this->logger = $logger;  
    $this->_dir = $dir;
}

/**
 * {@inheritdoc}
 */
public function apply()
{
    /** @var EavSetup $eavSetup */
    $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);

    $fileName = 'attributes.csv';
    $pubPath = $this->_dir->getPath('pub');
    $attributeFile = $pubPath.'/'.$fileName;
    $arrResult = array();
    if(($handle = fopen($attributeFile, 'r')) !== FALSE) {
        $row = 1;
        while(($data = fgetcsv($handle, 1000000, ',')) !== FALSE) {
            $col_count = count($data);
            $arrResult[] = $data;               
            $row++;
        }
        fclose($handle);
    } 
    $i = 0;
    foreach ($arrResult as $line) {
        if($i > 0){
            $attributeCode = $line[0];                    
            $attributeName = $line[1];
            $inputType = strtolower($line[2]);
            $options = $line[3];
          $type = 'int';
      $eavSetup->addAttribute(
        \Magento\Catalog\Model\Product::ENTITY,
           $attributeCode,
           [
             'type' => $type,
             'group' => 'General',
             'backend' => '',
             'frontend' => '',
             'label' => $attributeName,
             'input' => $inputType,
             'class' => '',
             'source' => '',
             'global' => ScopedAttributeInterface::SCOPE_GLOBAL,
             'visible' => true,
             'required' => false,
             'user_defined' => true,
             'searchable' => false,
             'filterable' => true,
             "filterable_in_search" => '1',
             'comparable' => false,
             'visible_on_front' => true,
             'used_in_product_listing' => true,
             'unique' => false,                 
             'option' => [
                'values' => $options,
               ],
             'system' => 1                    
             ]
           );
       }
     $i++;
   }

  }

public static function getDependencies()
 {
    return [];
 }

 /**
 * {@inheritdoc}
 */
 public function getAliases()
  {
     return [];
  }
}

The sample csv file is like below

The above code not creating the options, please someone help me on that how can we create a attribute with options. Thanks!!
