Ans: C)The pony is accelerating around the track.

Speed is a scalar quantity which expresses how fast an object is moving

Velocity (v)  is a vector which expresses both how fast the object is moving and in what direction it is moving

v = distance/time

Acceleration is the rate of change of velocity, hence it is a vector

a = v/t

A body will accelerate if there is a change either in the magnitude or direction  of velocity or if both change.

Since the pony is travelling around a track (circle) at constant speed, the magnitude does not change however, the direction keeps changing. Hence, the pony will be accelerating around the track.
