Answer: The correct answer is Option D.

Explanation:

Unstable isotopes are defined as the isotopes which have excess of neutrons as compared to the stable form of the nucleus of an atom.

These isotopes attain stability by undergoing a spontaneous nuclear decay. The isotopes which are unstable have another name and are known as radioactive isotopes or radioisotopes.

These isotopes undergoes decay by 4 processes: Alpha decay, beta decay, gamma emission and positron decay.

Hence, the correct answer is option D.
