Answer

Explanation
Solution
Taenia saginata belongs to phylum platyhelminthes, which are a flatworm. It is an intestinal parasite in humans causing taeniasis and cysticercosis in cattle. The body is made up of scolex, neck, and strobila. While the scolex has four suckers, there are no hooks. Lack of these rostellar hooks is an identifying feature of Taenia saginata.
So, the rostellar hooks are absent
