Which of the following processes represents a -decay ?

which of the following processes represents a gamma decay

Which of the following processes represents a $$\gamma $$ -decay ?

A. $$^A{X_z} + \gamma { \to ^A}{X_{Z - 1}} + a + b$$

B. $$^A{X_z}{ + ^1}{n_o}{ \to ^{A - 3}}{X_{Z - 2}} + c$$

C. $$^A{X_z}{ \to ^A}{X_Z} + f$$

D. $$^A{X_z} + {e_{ - 1}}{ \to ^A}{X_{Z - 1}} + g$$

Answer : $$^A{X_z}{ \to ^A}{X_Z} + f$$

Solution :
In $$\gamma $$ -decay, the atomic number and mass number do not change.
