Hey,

I would say that since it's accelerating perpendicular to its motion, it could be moving in a circle as the direction of the speed is tangent to the circle and perpendicular to the acceleration. The force is centripetal, towards the centre, and so is the acceleration.
The direction changes as the object moves in a circle and the speed stays constant as the acceleration has no effect on the speed since it is towards the centre and perpendicular to the speed.

An object accelerates in a direction that is always perpendicular to its motion implies that the object is moving in a circular motion or partially circular motion.
Should it be uniform or non-uniform circular motion? Once you have figured it out, the answer would become clear.
