Quizplus · Accepted Answer

The presence of bilateral symmetry, segmentation, true coelom, and complete digestive tract are characteristic of the phylum Annelida, which includes segmented worms such as earthworms, leeches, and marine worms. The other options do not fit all of the given characteristics. Cnidaria lack segmentation and a complete digestive tract, Platyhelminthes do not have a true coelom, and Nematoda are not segmented.
