Final answer:
In uniform circular motion, the acceleration of an object is both directed toward the center of the circular path and perpendicular to the object's velocity vector.
Step-by-step explanation:
In uniform circular motion, the direction of the object's acceleration is both B and C. The object's acceleration is directed toward the center of the circular path and is perpendicular to the object's velocity vector. This is because acceleration is in the direction of the change in velocity, which points directly toward the center of rotation.
