Let's analyze each statement to determine which one is wrong: Option A : A body can have zero velocity and still be accelerated. This statement is true. For example, at the highest point of its trajectory, a thrown ball has zero velocity, but it is still accelerating due to gravity. Option B : A body can have a constant velocity and still have a varying speed. This statement is false. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and the direction of the body are constant. Therefore, a body with constant velocity cannot have a varying speed. Option C : A body can have a constant speed and still have a varying velocity. This statement is true. A body moving in a circular path at a constant speed has a constantly changing velocity because the direction of the velocity vector changes even though its magnitude (speed) remains constant. Option D : The direction of the velocity of a body can change when its acceleration is constant. This statement is true. A common example is an object in free fall under gravity. The direction of its velocity changes as it goes up, stops, and comes back down, even though the acceleration (due to gravity) is constant. Therefore, the wrong statement is Option B : A body can have a constant velocity and still have a varying speed.
