For Maximum Angular Magnification in a Compound Microscope, the Objective $\left(f_{o}\right)$

For maximum angular magnification in a compound microscope, the objective focal length $\left(f_{o}\right)$ and the eyepiece focal length $\left(f_{e}\right)$ should be chosen so that

A) $f_{o}$ and $f_{e}$ are both the smallest available.
B) $f_{o}$ and $f_{e}$ are about the same.
C) $f_{o}$ and $f_{e}$ are both the largest available.
D) $f_{o}$ is the largest available; $f_{e}$ is the smallest available.
E) $f_{o}$ is the smallest available; $f_{e}$ is the largest available.
