(D) The magnifying power $(M)$ of a compound microscope is given by the formula $M \approx \frac{L}{f_o} 	imes \frac{D}{f_e}$,where $L$ is the tube length,$D$ is the least distance of distinct vision,$f_o$ is the focal length of the objective lens,and $f_e$ is the focal length of the eye-piece.From this relation,it is clear that $M \propto \frac{1}{f_o f_e}$.Therefore,to increase the magnifying power,the focal lengths of both the objective lens $(f_o)$ and the eye-piece $(f_e)$ should be decreased.
