Consider a radioactive material of half-life $1.0 \, minute$. If one of the nuclei decays now, the next one will decay

A

After $1$ minute

B

After $\frac{1}{{{{\log }_e}\,2}}$ minute

C

After $\frac{1}{N}$ minute, where $N$ is the number of nuclei present at that moment

D

After any time

Solution
