Answer the q.no. 2 with expalnation

Dear student, option A is true because a body like in vertically upward direction can have zero velocity but it still has acceleration due to gravity. Option B is also false that is a body can have constant velocity and still can be accelerated. Option C is also true because velocity has both direction and magnitude but speed has only magnitude, hence a body can have constant speed but varying velocity. Option D is also true because in circular motion direction of velocity changes while acceleration remains same.So ootionB is false.Thanks and regards.
