The correct options are
A There is a change in the speed of the object.
B There is a change in the direction of motion of the object.
The state of motion of an object changes, if:
1. There is a change in the speed of the object.
2. There is a change in the direction of the motion of the object.
If there is no change in either the speed or the direction of the object, then there is no change in state of motion of the object.
