The half-life period of a radioactive element $$E_1$$ is equal to the mean lifetime of another radioactive element $$E_2$$. Initially both the elements have the same number of atoms. Therefore,

A

$$E_2$$ will decay faster

B

$$E_1$$ will decay faster

C

$$E_1$$ and $$E_2$$ will decay at the same rate

D

Data insufficient
