Step-by-step explanation:
The acceleration of a sphere towards the center is known as a centripetal acceleration and it always points toward the center of the circular motion.
The sphere performing circular motion on the circumference of the circular path will have velocity and acceleration pointing in the same direction, tangentially outwards.
The tangentially outwards direction is perpendicular to the direction of centripetal acceleration.
Thus, Velocity and acceleration are perpendicular with acceleration towards the center.
Final Answer:
The correct option is: A
