Explanation

Enabling automatic RF tuning (Option C) directly addresses the root cause: all APs sharing the same channel creates severe co-channel interference, which degrades throughput and overall experience. Automatic RF tuning (a form of Radio Resource Management) dynamically assigns different channels to neighboring APs, eliminating that interference and restoring healthy terminal rates.

Why the distractors are wrong:

• A & B (weak signal access/offline control) manage which users connect, not why the channel is congested - they treat a symptom, not the cause, and would simply disconnect users rather than improve performance.
• D (load balancing) distributes users across APs to prevent overload, but if every AP is still on the same channel, the interference problem remains untouched.

Memory tip: Match the symptom to the root cause. "All APs on the same channel" screams channel conflict → the fix must be a channel/RF management tool. If the question mentions channel overlap or co-channel issues, the answer is almost always automatic RF/channel assignment.
