Which of the following equactions pick out the possible nuclear fusion reactions?

Options

A. `""_6C^13 + ""_1H^1 to ""_6C^14 + 4.3 MeV`
B. `""_6C^12 + ""_1H^1 to ""_7N^14 + 2MeV`
C. `""_7N^14 + ""_1H^1 to ""_8O^15 + 7.3 MeV`
D. `""_92U^235 + ""_0n^1 to ""_54Xe^140 + ""_36Sr^94 + ""_0n^1 + ""_0n^1 +y+2000 MeV`

Answer

C

Explanation

From the given reactions (a) is not possible because Atomic Number (Z) is not conserved. (b) is also not possible becausc A is not conserved. (d) is not possible because it is a fission reaction in which a heavy nucleus is split-up. (c) is the possible fusion reaction because both A and Z are conserved and two ligher nucilei fuse to form a heavy nuclei.
