option b   $7.5\ units$

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

$no=7.5\ units$ > given problem

therefore

the distance from point n to lm is equal to $7.5\ units$
