add_action('init', function() {
  if (function_exists('some_plugin_function')) {
    some_plugin_function();
  } else {
    error_log('Function missing');

Step 1: Understand the code logic
The code checks if some_plugin_function exists before calling it. If it does not exist, it logs 'Function missing'.
Step 2: Analyze the effect of removal
If another plugin removes or disables some_plugin_function, the condition fails and error_log is called.
Final Answer:
An error will be logged saying 'Function missing' -> Option A
Quick Check:
Missing function triggers error_log [OK]

Quick Trick: Check function_exists before calling to avoid fatal errors [OK]

Common Mistakes:

Assuming WordPress crashes without check
Thinking function runs even if missing
Believing plugin auto-deactivates on error
