For a body undergoing constant eastward acceleration along a horizontal line, any of the following are possible except
A) a westward velocity at an instant.
B) a westward velocity for an unlimited time.
C) zero net distance from a starting point at a time after motion has begun.
D) zero velocity for an instant.

Question
