Solution
The correct option is C Commensalism
Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consonant with its habits, as in the remoras that ride attached to sharks and other fishes. Remoras are also known as suckerfish or shark-suckers as they are commonly found attached to the bottom of sharks hitching a ride across the oceans. The Remora grows to about 18 inches and is brownish in appearance with a flat sucker-like appendage on its head that creates a partial vacuum allowing it to attach onto turtles, sharks, tuna, dugong, and even whales. They usually travel by attaching themselves onto a larger shark or fish, and feeds off the creature’s bacteria, parasites and waste like a cleaner fish. In return, the sharks and other host creatures do not harm their traveling companions.
So, the correct answer is 'Commensalism'.
