Consider a nuclear reaction :
`Aoverset(lambda_(1))rarrB+C`
and `Boverset(lambda_(2))rarrC`
A converts into B and to C with decay with decay constant `lambda_(1)` B is alos stable nucleus which futher decays into stable nucleus C with decay constant `lambda_(2).` Mark the correct statement(s)

A

`(dN_(C))/(dt)=-(lambda_(1)N_(A)+lambda_(2)N_(B))`

B

`(dN_(A))/(dt)=-lambda_(1)N_(A)`

C

`(dN_(A))/(dt)=(lambda_(1)N_(A)+lambda_(2)N_(B))`

D

`(dN_(B))/(dt)=lambda_(1)N_(A)+lambda_(2)N_(B)`
