Magento 2 : how to get Product select attribute option value on product page

Step 1: Add Block for an attribute on catalog_product_view.xml

<block class="Magento\Catalog\Block\Product\View\Description" name="page.main.brand" template="Magento_Catalog::product/view/brand.phtml">
      	<arguments>
        <argument name="at_call" xsi:type="string">getBrand</argument>
        <argument name="at_code" xsi:type="string">brand</argument>
        <argument name="css_class" xsi:type="string">brand</argument>
        <argument name="at_label" xsi:type="string">default</argument>
        <argument name="add_attribute" xsi:type="string">itemprop="brand"</argument>
      </arguments>
      </block>

Step 2: move it to your location

<move element="page.main.brand" destination="product.info.main" after="page.main.title"/>

$_product = $block->getProduct();
 
$_code = $block->getAtCode();
$_className = $block->getCssClass();
$_attributeLabel = $block->getAtLabel();
$_attributeType = $block->getAtType();
$_attributeAddAttribute = $block->getAddAttribute();
 
if ($_attributeLabel && $_attributeLabel == 'default') {
$_attributeLabel = $_product->getResource()->getAttribute($_code)->getFrontendLabel();
}
 
$_attributeValue =$_product->getResource()->getAttribute($_code)->getFrontend()->getValue($_product);
 
?>
 
<?php if ($_attributeValue): ?>
<div class="product attibute <?php echo $_className?>">
<?php /*?><?php if ($_attributeLabel != 'none'): ?><strong class="type"><?php echo $_attributeLabel?></strong><?php endif; ?><?php */?>
