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

Options

A. `-(1-(L)/(f_(0)))((D)/(f_(e)))`
B. `-(L)/(f_(0))(1+(D)/(f_(e)))`
C. `-(L)/(f_(0))(1-(D)/(f_(e)))`
D. `-(L)/(f_(0)).(D)/(f_(e))`

Answer

D
