Solution

The correct option is C Taenia saginata
Taenia saginata can be distinguished from its sister species. Taenia solium, by the absence of these rostellar hooks on the scolex. The absence of hooks on the rostellum has earned another name for the species, the “unarmed tapeworm.”
Therefore, the correct answer is option A.
