Answer: B
Stabilizing inner ear bones to protect hearing
Verified · wikipedia.org, Kenhub
You might think the smallest muscle has a minor role, but the stapedius muscle, measuring just over one millimeter, stabilizes the stapes (the body's smallest bone). When sounds are too loud, it contracts to reduce the stapes' vibration, preventing inner ear damage. It acts as a crucial 'shock absorber' for your hearing.
The next time you hear a sudden loud noise, try to notice if your ears feel a slight tightening – that's the stapedius muscle at work. Challenge that friend who's always saying 'what did you say?' — see if they can guess how a tiny muscle in their ear protects their hearing.
