D Correct answer
Explanation

Human placentas are classified as chorio-allantoic (derived from both membranes), deciduate (part of the uterine lining is shed at birth), and haemochorial (maternal blood directly bathes the chorionic villi). Since all these descriptions apply to the human placenta, the correct answer is all of the above.
