Solution

The correct option is B Their accelerations are equal but their velocities are equal and opposite
Their accelerations are equal. Gravity is accelerating the one going downwards, and deccelerating the one going up, and gravity is a constant. Since gravity is the only accelerating force acting on them, their acceleration is equal, ( $9.8 m / s^{2}$ downwards.) However, their velocities are not equal. They are opposite (one is going up, one's going down.)
