How can HTML validation and debugging tools help troubleshoot issues with preselected options in PHP-generated SELECT dropdowns?

When troubleshooting issues with preselected options in PHP-generated SELECT dropdowns, HTML validation and debugging tools can help identify any syntax errors or inconsistencies in the code that may be causing the problem. By using tools like the W3C Markup Validation Service or browser developer tools, you can pinpoint where the issue lies and make the necessary corrections to ensure that the preselected options are displayed correctly. 

<?php
$options = array("Option 1", "Option 2", "Option 3");
$selectedOption = "Option 2";

echo "<select>";
foreach($options as $option) {
    if($option == $selectedOption) {
        echo "<option value='$option' selected>$option</option>";
    } else {
        echo "<option value='$option'>$option</option>";
    }
}
echo "</select>";
?>
