The correct option is (c).
Explanation:
According to conservation of mass number
10 + 4 = 13 + 1
According to conservation of charge number,
5 + 2 ≠ 7 + 7
Hence (a) is not possible.
According to conservation of charge number,
93 = 94 -1
According to conservation of mass number,
239 = 239
Hence (c) is possible.
According to conservation of mass number,
11 + 1 = 12
According to conservation of charge number,
7 + 1 ≠ 6 - 1
Hence (d) is not possible.
2311Na + 11H also satisfies both the conservation of mass number and charge but reaction is not a nuclear reaction.
