Light takes of `t_(1)` to travel a distance `x_(1)` in vacuum and the same light takes time `t_(2)` to travel a distance `x_(2)` in a medium. The critical angle for that medium is

A

`sin^(-1)((x_(2)t_(2))/(x_(1)t_(1)))`

B

`sin^(-1)((x_(1)t_(2))/(x_(2)t_(1)))`

C

`sin^(-1)((x_(1)t_(1))/(x_(2)t_(2)))`

D

`sin^(-1)((x_(2)t_(1))/(x_(1)t_(2)))`
