#### Samples of two radioactive nuclides A and B are taken. $\lambda$A and $\lambda$B are the disintegration constants of A and B respectively. In which of the following cases, the two samples can simultaneously have the same decay rate at any time?(a) Initial rate of decay of B is the same as the rate of decay of A at t = 2h and λB < λA(b) Initial rate of decay of A is twice the initial rate of decay of B and $\lambda$A > $\lambda$B(c) Initial rate of decay of A is twice the initial rate of decay of B and $\lambda$A = $\lambda$B(d) Initial rate of decay of B is twice the initial rate of decay of A and $\lambda$A > $\lambda$B

The correct answers are the options,

(a) Initial rate of decay of B is the same as the rate of decay of A at t = 2h and λB < λA

(b) Initial rate of decay of A is twice the initial rate of decay of B and λA > λB
