a an elephant, standing still.
b a bullet, moving at 700 m/s.
c a car moving slowly, but accelerating rapidly.
d a skydiver falling at a constant velocity

Explanation:

Inertia is directly related to mass. The more massive an object, the greater its inertia, regardless of its motion state. An elephant has a much larger mass compared to a bullet, a car, and a skydiver.

Answer:

A. An elephant, standing still.
