Correct choice is (b) Q value

Easy explanation: In a nuclear reaction, the sum of masses before the reaction is greater than the sum of masses after the reaction. The difference in masses appears in the form of energy following the law of inter-conversion of mass and energy. Thus, the energy released in a nuclear reaction is called a Q value of a reaction.
