Sample of two radioactive nuclides `A` and `B` are taken. `lambda_(A)` and `lambda_(B)` are the disintergration constants of `A` and `B` respectively. In which of the following cases, the two sample can simultaneously have the same decay rate at any time ?A. Initial rate of decay of A is twice the initial rate of decay of B and `lambda_A=lambda_B`.B. Initial rate of decay of A is twice the initial rate of decay of B and `lambda_Agtlambda_B`.C. Initial rate of decay of B is twice the initial rate of decay of A and `lambda_Agtlambda_B`.D. Initial rate of decay of B is twice the initial rate of decay of A at t=2h and `lambda_B=lambda_A`
