C Correct answer
Explanation

Force is defined as the rate of change of momentum (dp/dt), which is Newton's actual second law. F = ma is derived from this when mass is constant. Rate of change of acceleration would be jerk (da/dt), and rate of change of velocity is acceleration, not force. Mass * acceleration is a consequence, not the definition.
