Badd_action('init', function() { if (is_single()) { echo 'Thanks for reading!'; } });

Cadd_action('wp_head', function() { if (is_single()) { echo 'Thanks for reading!'; } });

Dadd_action('wp_footer', function() { echo 'Thanks for reading!'; });

Step-by-Step Solution

Solution:

Step 1: Identify the correct hook for footer output
'wp_footer' runs after footer content loads, so it's the right hook to add footer messages.
Step 2: Apply condition to show message only on single posts
Using is_single() inside the hooked function ensures the message appears only on single post pages.
Final Answer:
add_action('wp_footer', function() { if (is_single()) { echo 'Thanks for reading!'; } }); -> Option A
Quick Check:
Footer hook + condition inside function = correct usage [OK]

Quick Trick: Use wp_footer hook with is_single() condition inside function [OK]

Common Mistakes:
