A radioactive nuclide can decay simultaneously by two different processes which have decay constants `lambda_(1)` and `lambda_(2)`. The effective decay constant of the nuclides is `lambda`.

A

`lamda = lamda _(1) + lamda _(2)`

B

`lamda = 1/2 (lamda _(1) + lamda _(2))`

C

`(1)/(lamda) = (1)/(lamda _(1)) + (1)/(lamda _(2))`

D

`lamda = sqrt(lamda _(1) lamda _(2))`
