(C) When an excited nucleus emits $\gamma$-radiation,it transitions from a higher energy state to a lower energy state.The process is represented as: $_{Z}X^{A} \xrightarrow{\gamma 	ext{ decay}} _{Z}X^{A} + \gamma$.Since $\gamma$-rays are high-energy electromagnetic photons and carry no charge or mass,the emission of $\gamma$-radiation does not change the number of protons or neutrons in the nucleus.Therefore,both the mass number $(A)$ and the atomic number $(Z)$ remain unchanged.
