Solution
The correct option is A Speed
In circular motion, the direction of the revolving body changes at every point of the circle. Hence, all the vector quantities will change at every point of the circular motion. Speed is a scalar quantity and its magnitude remains the same at every point of the circular motion. Thus, option a is correct.
