B) It suddenly makes a transition into a state of smaller uncertainty in position and greater uncertainty in velocity.
C) It suddenly makes a transition into a state of greater uncertainty in position but smaller uncertainty in velocity.
D) It suddenly makes a transition into a state of smaller uncertainty in position, with no change in its uncertainty in velocity.
E) It makes a gradual transition to a state of smaller uncertainty in position and greater uncertainty in velocity.
