I’m which type of radioactive decay does the nucleus become more stable without changing its identity

Beta plus decay
Gamma

decay

In gamma decay, the nucleus becomes more stable without changing its identity. During this type of radioactive decay, a nucleus releases high-energy gamma radiation, which consists of electromagnetic waves with no charge or mass. Unlike alpha and beta decays, gamma decay does not involve the emission of particles. Instead, it occurs when an excited nucleus transitions to a lower energy level by releasing excess energy in the form of gamma rays. The identity of the nucleus remains the same after gamma decay.
