Best answer
The correct choice is (a) Hooks and suckers

To elaborate: The body of Tapeworm is divided into Scolex, Neck and Strobila. At the apex of scolex is a prominent mobile cone, the rostellum which is armed with 22 to 32 curved chitinous hooks, arranged in two rows. The scolex also bears four hemispherical, highly muscular sectorial organs, the true suckers. The suckers and hooks are the organs of attachment to the intestinal wall.
