The correct answer is: D) a platyhelminth

A platyhelminth is a simple unsegmented soft-bodied flat worm with bilateral symmetry.

Since they don't have any respiratory and circulatory organs, respiration occurs through the whole surface of the body. So, this type of worm has a great surface area in order to absorb more oxygen.
