Which statement about gamma rays is true according to the material?

• A. Gamma rays are high-energy photons emitted during a process that changes the element.
• B. Gamma rays are emitted only during fusion.
• C. Gamma rays are high-energy photons emitted when energy is released without changing the element.
• D. Gamma rays always transform the element into a different element.

Answer: (C)

Gamma rays are high-energy photons released when a nucleus sheds excess energy but keeps the same number of protons and neutrons. In other words, the nucleus transitions from a higher energy state to a lower one without changing its identity, so the element remains the same even as energy leaves as a gamma photon. That’s why the statement describing energy release as a gamma photon without changing the element is true. Gamma emission can occur after other processes, like beta decay, as the daughter nucleus relaxes from an excited state, and it does not by itself transform the element into a different element.
