Answer:
B. 32
Explanation:
We have been given that B, D, and F are midpoints of the sides of Angle ACE.
To solve for the length of side AC, we will use mid-segment theorem, which states that the segment connecting mid points of two sides of a triangle is parallel to third side of triangle and half the measure of third side.
We can see that side DF is parallel to side AC, so measure of side AC will be 2 times the measure of DF.



Therefore, the measure of side AC is 32 units and option B is the correct choice.
