Light takes `t_(1)` second to travel a distance x cm in vacuum and the same light takes `t_(2)` second to travel 10x cm in medium. The critical angle for the corresponding 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)))`
