The answer is the option a. <span>a. a ball moving at a constant speed around a circular track.
Acceleration is the change in velocity. This change may be either on speed or on direction (or both).
A ball moving at a constant speed around a circular track is continously changing its direction so it is under acceleration (centripetal acceleration).
All the other cases are of objects moving at the constant speed and in straight line, i.e. constant velocity, which is not accelerating.

Typically no. Displacement can be in multiple directions as a vector. of something is traveling only along x, then it would be true though this is usually not the case.
