The correct option is A Tapeworm
Hooks and suckers are present in tapeworm. Tapeworm is an intestinal parasite and is in phylum Platyhelminthes. It gets attached to the host intestine with the help of hooks. In some organisms such as Flukes, there are one of the two types of suckers (oral suckers) help to imbibe the food from the host.
Hooks and suckers are absent in earthworm, Hydra and Pleurobrachia. They are not parasites and are all free-living animals.
