Answer:
The parasitic organism that is shown in the ilustration is planarian.
Explanation:
A is not correct because the fluke has much different phisical appearance, being roughly leaf-shaped and flat.
B is not the correct option because the amoeba is a much simpler organism than the depicted one, and it is not a parasitic one for that matter.
C is not correct because the tapeworm is much longer, flatter, and exhibits darker coloration.
D is correct because the organism on the illustration matches the physical appearance of a planarian worm, which is also a parasitic organism.
