Velocity is a vector quantity.
It has both magnitude as well as direction.
Velocity is equivalent to the speed of a body along with the direction of motion.
Explanation for the incorrect option(s)
Momentum: Momentum is a physical quantity that is a product of the mass of a particle and its velocity.
Speed: The rate of change of distance is known as speed.
Acceleration: The rate of change of velocity is known as acceleration.
Hence, option C is correct.
