The time required for
a. decay period.
b. lifetime.

Concept introduction:
Radioactive decay is the process that involves the emission of radiation by an unstable atomic nucleus. The atomic nucleus loses its energy. The process is spontaneous. It is also known as nuclear radiation.
Reason for correct answer:
Radioactive decays are first order reactions and the half-life for first order reactions does not depend on its initial amount.
The time required for the concentration of the reactant to reduce to half of its initial concentration gives the half-life of the reaction. In other words, at half-life of the element, the half of the original sample is reacted or disintegrated.
Reason for incorrect options:
(a) Decay period does not corresponds to the time required for
