Correct Answer: Option D

Barnacles are exclusively marine crustaceans, related to crabs and lobsters. They are commonly found attached to hard surfaces like rocks, piers, and boat hulls in shallow and tidal (intertidal) waters within marine habitats.  Both organisms are characteristic of rocky shores within marine ecosystems.
