Solution:

Step 1: Check if the section exists
The control references 'footer_section', but this section was never added with add_section().
Step 2: Understand control behavior without a valid section
Controls must belong to existing sections; otherwise, they won't display in the Customizer UI.
Final Answer:
The control will not display because the section does not exist -> Option A
Quick Check:
Control needs valid section to display = true [OK]

Quick Trick: Controls need existing sections to show [OK]

Common Mistakes:

Assuming setting fails to save without section
