Hint: The case between the suckerfish and the shark is that the suckerfish gets benefited from the shark while the shark is neither benefited nor harmed by the suckerfish. The suckerfish attaches to the dorsal fin of the shark and feeds on the pieces that are present on the sea bed.

Complete answer:
The relationship between the suckerfish and the shark is the commensalism type of relation in which between the two species one gets benefited while the other is neither benefited or harmed. The suckerfish gets attached to the shark with the help of the sucker that is present on their head and they become fixed with the dorsal side of the shark and moves along with the shark and gets its food but becomes separated from the shark to collect the particles that float on the sea beds.
So, both the assertion and reasons are incorrect.

Note: The suckerfish attached with the shark move to the different areas and without spending its energy and the shark has no harm by the presence of suckerfish. The suckerfish also eats the parasites attached to the skin of the shark.
