Which of the following process represents a `gamma- decay`?

Options

A. `.^(A)X_(Z)+gammararr.^(A)X_(Z-1)+a+b`
B. `.^(A)X_(Z)+gammararr.^(A)X_(Z-1)+a+b`
C. `.^(A)X_(Z)rarr.^(A)X_(Z)+f`
D. `.^(A)X_(Z)+e_(-1)rarr.^(A)X_(Z-1)+g`

Answer

C

Explanation

During `gamma`-decay atomic number `(Z)` and mass number `(A)` does not chanrge. So the correct option is `(C )` because in all other options either `Z, A` ro both is`//`are changing.
