Answer: A
Pseudo-metameric segmentation is a feature of Cestoda.
The body of a tapeworm is a chain (strobila) of proglottids budded off from the neck. They look like segments, and each contains a complete set of reproductive organs, but they are not true metameres: they are formed by budding from the front, not as repeated units with a segmented coelom, muscles and nerves, so the condition is called pseudometamerism.
Nematodes and trematodes are unsegmented, and Ectoprocta (bryozoans) are colonial animals whose individuals are not segmented.
