Solution

The correct options are
A Opposite to each other
D Parallel to each other
when the cycle is accelerating in the forward direction both the velocity and the acceleration are directed in the same direction, but as the brake is applied the cycle will still have the same direction in velocity(cause it's still moving forward) but it is retarding that is it's acceleration is in the opposite direction.
It is parallel to each other.
