C. atomic phenomena D. spontaneous Phenom​

Answer 1

Answer :- (B) Natural Phenomena

Answer 2

Atomic phenomenon is not applicable for radioactivity.

• Radioactivity is a process by which unstable atomic nuclei degenerate to release energy and obtain a more stable electronic configuration.
• It occurs spontaneously in nature.
• Since it involves the emission of alpha, beta, or gamma radiation from the nuclei of an atom, it is a nuclear phenomenon.
• Hence the options natural phenomenon, nuclear phenomenon, and spontaneous phenomenon are correct.
