Which force is most directly responsible for radioactive beta decay?

electromagnetic force

strong interaction

gravitational interactions

weak interaction

Answer;

weak interaction

Explanation; The weak force is one of the four fundamental forces that govern all matter in the universe (the other three are gravity, electromagnetism and the strong force). Weak interaction is the mechanism of interaction between subatomic particles that causes radioactive decay and thus plays an essential role in nuclear fission. Only weak interactions can cause the decay of fundamental particles.
