B. a force equal to zero

Hector Farmer · Answer 2

This is an example of Newton's first law of motion:

An object at rest will remain at rest unless an unbalanced force acts upon it. Similarly, a moving object will remain moving in a straight line at constant velocity unless an unbalanced force acts upon it.

The answer is C.
