A ray of light is incident normally on one face of a prism of refracting angle A. After travelling through prism, the ray emerges from the second refracting surface making an angle of deviation of `delta`. The refractive index of the material of prism is

A

`frac(sin(frac(A+delta)(2)))(sin(frac(A)(2))`

B

`frac(sinA)(sindelta)`

C

`frac(sindelta)(sinA)`

D

`sin(A + delta)(sin(A))`
