Which outcome results when metastable Technetium-99m undergoes isomeric transition?

A)Emission of a gamma ray
B)Capture of inner shell electron
C)Production of an alpha particle
D)Spontaneous fission into smaller nuclei

💡 Explanation

Isomeric transition is a type of radioactive decay where a nucleus transitions to a lower energy state, resulting in the emission of a gamma ray photon. Therefore, gamma emission occurs, rather than electron capture or particle emission, because Technetium lowers its excited state.
