Answer;

C. An object can have acceleration with negative velocity.

Explanation; Acceleration is a measure of the change in velocity over time. The change in velocity is measured in meter per second (m/s), and time interval is measured in second (s). Therefore, acceleration measures the change in meters per second every second [ (m/s) / s], namely meters per second per second or meters per second squared (m/s2). If an object has zero acceleration, its velocity doesn't have to be zero. Acceleration is a measure of the change in velocity over time. Zero acceleration means there is no change in velocity over time, namely constant velocity.
