The correct answer is:
**The velocities should be equal in magnitude and opposite in direction.**
This is because, for the total momentum of a system to be zero, the momentum of one body must be equal in magnitude and opposite in direction to the momentum of the other body. Since they are identical bodies, their masses are the same, and thus their velocities must also be equal in magnitude but opposite in direction.
