Theorem: a line parallel to one side of a triangle divides the other two proportionately.

in the figure below, segment de is parallel to segment bc and segment ef is parallel to ab.

the figure shows triangle abc with segments de and ef. point d is on side ab, point e is on side ac and point f is on side bc. segment ad is 6, segment ae is 12, segment ec is 18, and segment fc is 24

which statement can be proved true using the given theorem?

segment bd = 12

segment bd = 4

segment bf = 16

segment bf = 9
