Hint:The direction of motion varies at each moment, either on the curved path or usually on the Circular Path, so any movement travelling on a circular or curved path cannot be continuous. It does not mean velocities and speeds.

Step by Step solution:
Here we have to see which quantities change and which remain constant.
As we all know that all the quantities are divided into two categories; they are vectors and scalars.

If we talk about vectors, the quantities that have magnitude and also direction are called vector quantities. For example, velocity, acceleration, force, etc.

However the scalars are quantities that have only magnitude. they do not have direction. You will never hear anyone say that the mass of the block is 2 kilograms towards the right. This is because mass is a scalar quantity.

On a curved road, the flow switches instantaneously. So, since a vector has magnitude and direction, it cannot stay constant along a curved lane. The velocity and acceleration are vectors in the above choices, so they can shift. There are no instructions for speed and degree of acceleration, so they will continue on a curved track.

Hence A and D are the correct options.

Note: In the question here is asking ''Is it possible'', this means which case can exist in a given option. So, only the magnitude of the acceleration may be constant and the Speed may be constant. But other two conditions can never be true in the motion along the curved path.
