#### Question - 2

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 Intial rate of decay of A is twice the initial rate of decay of B and \({ \lambda }_{ A }\) = \({ \lambda }_{ B }\)
- B Intial rate of decay of A is twice the initial rate of decay of B and \({ \lambda }_{ A }\) > \({ \lambda }_{ B }\)
- C Intial rate of decay of B is twice the initial rate of decay of A and \({ \lambda }_{ A }\) < \({ \lambda }_{ B }\)
- D Initial rate of decay of B is always same
