It is not your enemy, yet we still beat it. What is it?

Choose an answer

A.A punching bag
B.A rug
C.A gong
D.A drum
Hint: It's a 2-word phrase with 5 letters, starting with "A".

Answer

A drum

Why this is the answer

This plays on the double meaning of 'beat': striking a drum is called beating it, even though it's an instrument, not an opponent.
