Figure shows two glass slabs placed one above the other in air. Refractive indices of glass slabs are `mu_(2)` and `mu_(3)` and that of air is `mu_(1)`. A ray of light enters and follows a path as shown in figure. It can be concluded that

A

`mu_(1)=mu_(2)=mu_(3)`

B

`mu_(1)ltmu_(2)ltmu_(3)`

C

`mu_(1)gtmu_(2)=mu_(3)`

D

`mu_(1)gtmu_(2)gtmu_(3)`
