Since, nothing is provided, we assume completely elastic collision (bodies don't stick and move together). In this case, after collision both the bodies will move in opposite directions with the same velocity (v). Hence, common velocity (relative velocity of one with respect to other) will be 2v.

Hence, the answer B is correct.
