A bi-convex lens is cut from the middle ...

A bi-convex lens is cut from the middle as shown in figure. Refractive index of material of lens is `(3)/(2)`. Now lens-1 (as shown in figure) is immersed in a liquid of refractive index `mu_(0)`. By doing so it is observed that its focal length becomes equal to lens-2. What is the value of `mu_(0)` ?

A

`1.3`

B

`1.1`

C

`1.4`

D

`1.2`
