What are the benefits of using backticks and separating the primary key value in the option element when populating a dropdown menu in PHP?

Using backticks and separating the primary key value in the option element when populating a dropdown menu in PHP ensures that the primary key values are properly enclosed and distinct within the HTML markup. This helps prevent any potential conflicts or errors when retrieving and processing the selected value from the dropdown menu in the backend code. 

<select name="dropdown">
<?php
// Assume $results is an array of data fetched from a database query
foreach ($results as $row) {
    echo '<option value="' . $row['id'] . '">' . $row['name'] . '</option>';
}
?>
</select>
