Jack and Mary view the same microorganism through the same compound microscope. Mary's near point distance, $N_M$, is twice as large as Jack's near point distance, $N_J$. If Mary sees the microorganism with magnification $M_M$, with what magnification does Jack see it?
A $M_M/2$
B $2M_M$
C $4M_M$
D $8M_M$
E $M_M/4$
