Suppose, the daughter nucleus in a nuclear decay is itself radioactive. Let `lambda_p and lambda_d` be the decay constants of the parent and the daughter nuclei. Also, let `N_p and N_d` be the number of parent and daughter nuclei at time `t`. Find the condition for which the number of daughter nuclei becomes constant.

A

`lambda_p=lambda_d`

B

`lambda_p//N_p=lambda_d//N_d`

C

`(lambda_p)/(N_d)=(lambda_d)/(N_p)`

D

The number of daughter nuclei cannot become constant.
