At time `t=0 N_(1)` nuclei of decay constant `lambda_(1)& N_(2)` nuclei of decay constant `lambda_(2)` are mixed. The decay rate of the mixture at time 't' is:

A

`N_(1)N_(2)e^(-(lambda_1+lambda_2)t)`

B

`+((N_(1))/(N_(2)))e^(-(lambda_1+lambda_2)t)`

C

`+(N_1lambda_1e^(-lambda_1t) + N_(2)lambda_2e^(-(lambda_2t)))`

D

`+N_1lambda_1 + N_(2)lambda_2 e^(lambda_1+lambda_2)_(t)`
