Activity of a radioactive substance is A...

Activity of a radioactive substance is `A_(1)` at time `t_(1)` and `A_(2)` at time `t_(2)(t_(2) gt t_(1))` , then the ratio of f`(A_(2))/(A_(1))` is:
a) `e^(lambda(t_(2)+t_(1)))`
b) `e^(lambda(t_(1)-t_(2)))`
c) `e^(-lambda(t_(1)+t_(2)))`
d) `(t_(2))/(t_(1))`

A

`e^(lambda(t_(2)+t_(1)))`

B

`e^(lambda(t_(1)-t_(2)))`

C

`e^(-lambda(t_(1)+t_(2)))`

D

`(t_(2))/(t_(1))`
