Solution

## The correct option is B fly in opposite direction with same momentum Since no external force is acting on the system then its momentum will be conserved.So initially shell was at rest hence zero momentum and thus finally two pieces will fly in opposite direction with same momentum to maintain the total momentum equals to zero as before.
