The given statement about the nuclear reaction as three (alpha decay, beta decay and fusion) is false.
Answer: Option B
Explanation:
The branch of the study of the nucleus is known as nuclear physics. There are four types of nuclear reaction namely,
1. Fission
2. Fusion
3. Nuclear Decay
4. Transmutation
As the name suggests, when two or many parts of the nucleus fuse together, it is a nuclear fusion reaction. And when one nucleus is divided or splits into two or many parts separately, it is the nuclear fission reaction.
In nuclear decay, the unstable isotope of the element is automatically converted to the new element by ionizing radiation whereas its reverse process called transmutation.
