The double-pore tapeworm is:

Explanation:
The main idea here is recognizing a tapeworm by where it attaches to the intestinal lining. The term “double-pore tapeworm” refers to having two attachment grooves (bothria) on the scolex that anchor the worm in the host’s gut. Moniezia expansa has these two attachment grooves, which is why it’s described as the double-pore tapeworm. The other organisms listed are not described by this two-groove attachment feature: Paragonimus kellicotti is a lung fluke, not a tapeworm; Dipylidium caninum is a flea tapeworm and is noted for other characteristics such as its proglottids and eggs; Echinococcus granulosus is a hydatid tapeworm with a different life-cycle and morphology.
