D. a 50 kg boulder suspended from a cliff

Answer 1

A 50 kg boulder suspended from a cliff.

Step-by-step explanation:

In this case, that totally depends on the velocity of the object, In case of car, that's just parked so the velocity is zero and a fish can't swim with higher velocity than a boulder which is suspended from a cliff.

Hope it helps!<3
