JEE Question 2007 paper I

In the options given below, let E(A,B)X denote the rest mass energy of a nucleus of material X and E(n)of a neutron. The correct option is
(A)E(236,92)U > E(137,53)I + E(97,39)Y + 2E(n)
(B)E(236,92)U < E(137,53)I + E(97,39)Y + 2E(n)
(C)E(236,92)U < E(140,56)Ba + E(94,36)Kr + 2E(n)
(D)E(236,92)U = E(140,56)Ba + E(94,36)Kr + 2E(n)

Sol: Ans [A]
(236,92)U breaks into smaller atoms and gives out energy.
