Answer 1

Decay constant of B is greater than that of A but still its decay rate becomes equal to that of A at a later instant.

Answer 2

Decay constant of A is greater than that of B but it does not always decay faster than B.

Answer 3

Decay constant of B is greater than that of A but its decay rate is always smaller than that of A.

Answer 4

Decay constant of A is greater than that of B, hence A always decays faster than B.
