• B. Movement of eye lids
• C. Closing and opening the valves of heart
• D. Movement of pinnae

Answer 1

Answer: (C)

Closing and opening the valves of heart

The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae. They help in closing and opening the valves of heart and contract to prevent backward flow of ventricular blood into the atrial cavities.

So, the correct answer is option C.
