Q.
Match the List I with List II [2025]

List I List II

(A) ${}_{0}^{1}n +_{92}^{235} U \to_{54}^{140} Xe +_{38}^{94} Sr + 2_{0}^{1} n$ (I) Chemical reaction

(B) $2 H_{2} + O_{2} \to 2 H_{2} O$ (II) Fusion with +ve Q value

(C) ${}_{1}^{2}H +_{1}^{2} H \to_{2}^{3} He +_{0}^{1} n$ (III) Fission

(D) ${}_{1}^{1}H +_{1}^{3} H \to_{1}^{2} H +_{1}^{2} H$ (IV) Fusion with −ve Q value

Choose the correct answer from the options given below:

1 A–II, B–I, C–III, D–IV

2 A–III, B–I, C–II, D–IV

3 A–II, B–I, C–IV, D–III

4 A–III, B–I, C–IV, D–II

Ans.
(2)

(A) is fission reaction
