The focal lengths of the objective and of the eye-piece of a compound microscope are `f_(0)` and `f_(e)` respectively. If `L` is the tube length and `D`, the least distance of distinct vision, then its angular magnification, when the image is formed at infinity, is

A

`(1 - (L)/(f_(o)) ) ((D)/(f_(e)))`

B

`(1 + (L)/(f_(o))) ((D)/(f_(e)))`

C
