Answer to Question 1

D

Answer to Question 2

If an object has only (pure) translational motion every particle in it has the same instantaneous velocity, which means that the object is not rotating. An object may have only (pure) rotational motion - motion about a fixed axis if all of the particles of the object have the same instantaneous angular velocity and travel in circles about the axis of rotation.
