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

Options

A. `.^(A)X_(Z) + gamma rarr .^(A)X_(Z-1) + a + b`
B. `.^(A)X_(Z) + .^(1)n_(0) rarr .^(A-3)X_(Z-2) + o`
C. `.^(A)X_(Z) rarr .^(A)X_(Z) + f`
D. `.^(A)X_(2)+e_(-1)rarr .^(A)X_(A-1)+g`

Answer

C

Explanation

During `gamma-` decays atomic number (Z) and mass number (A) does not change. So, the correct option is (c) because in all other options either Z, A or both is/are changing.
