Why does the Yoast SEO snippet below cause a fatal error?

Look at this code added to functions.php: add_filter('wpseo_title', function() { return $custom_title; }); Why does this cause a fatal error?

Wordpress

add_filter('wpseo_title', function() {
  return $custom_title;
});

A Because 'wpseo_title' is not a valid filter hook in Yoast SEO.

B Because $custom_title is undefined inside the anonymous function scope.

C Because the function should echo the title, not return it.

D Because add_filter requires a priority argument after the callback.

💡 Hint

Think about variable scope inside anonymous functions in PHP.

The variable $custom_title is not defined inside the anonymous function, causing a fatal error. Variables must be passed in or defined inside the function.

B The sitemap URL redirects to the homepage automatically.

C The sitemap URL shows the default WordPress sitemap instead.

D The sitemap URL still shows the sitemap but with no URLs inside.
