What is radioactive decay?
A. The splitting of a nucleus to form smaller nuclei
B. The release of photons by electrons losing energy
C. The formation of a larger nucleus by joining nuclei
D. The spontaneous breakdown of a nucleus

Radioactive decay is the process in which a nucleus loses energy by emitting alpha, beta or gamma radiation. Due to this process the nucleus' energy reduces which leads to stability of an atom.

So we can conclude that the splitting of a nucleus to form smaller nuclei is known as radioactive decay.
