The velocity of an object is its speed in a particular direction. Velocity can also be defined as rate of change of displacement or just as the rate of displacement. It is a vector physical quantity with dimension LT(-1). In the SI (metric) system, it is measured in meters per second (m/s). The scalar absolute value (magnitude) of velocity is speed.
Since velocity is defined as a vector quantity, both speed and direction are required to define it. You can not have a speed and no direction. Make sure you have the direction, for example: in reverse, forwards, north, towards the beach, ect. For example, "5 metres per second" is a speed and not a vector, whereas "5 metres per second east" is a vector

C is the correct answer.
A is the first integral of velocity
B is the definition for rate of speed, aka motion.
D is the second derivative of velocity, measured in jerks.
