The correct option is C Suckers
Taenia saginata is commonly known as the beef tapeworm. It is an intestinal parasite in humans causing taeniasis which is a type of helminthiasis and cysticercosis in cattle. Cattle are the intermediate hosts where larval development occurs, while humans are definitive hosts contains the adult worms. Humans get infected by eating raw or undercooked meat. Once reaching the jejunum, the inverted scolex becomes evaginated to the exterior under stimuli from the digestive enzymes of the host. Using the scolex suckers it attaches to the intestinal wall. The larva mature into adults about 5 to 12 weeks later. Adult worms can live about 25 years in the host. Beef tapeworm scolex does not have hooks, rostellum, and spins. So, option C is correct.
