Two radioactive materials `X_(1)` and `X_(2)` have decay constant `11 lambda` and `lambda` respectively. If initially they have same number of nuclei, then ratio of number of nuclei of `X_(1)` to `X_(2)` will be `(1)/(e^(2))` after a time
A. `(1)/(10 lambda)`
B. `(1)/(11 lambda)`
C. `(11)/(10 lambda)`
D. `(1)/(9 lambda)`
