Not quite. The correct answer is highlighted.

Correct answer to question 66 (Air Brakes): A dragging or improperly adjusted brake can create constant friction that builds excess heat even when the driver isn't actively braking hard

Why

A brake that's dragging because of poor adjustment keeps generating friction even without hard braking, and that extra friction shows up as unusual heat after a normal trip.
