Define marine.

fed milk from mother's body
an orgasmic leukocyte
molten rock in the earth's crust
inhabiting the sea

The correct answer is: inhabiting the sea

The term "marine" refers to anything related to the sea or ocean. This includes a broad range of topics such as marine life, ecosystems, and geographic features associated with saltwater environments. For instance, organisms like fish, corals, and whales are all classified as marine because they inhabit oceanic waters. The other options do not pertain to the sea: one refers to a biological process related to mammals, another to a type of immune cell, and the last describes geological materials, none of which connect directly to marine environments. Understanding that "marine" relates specifically to the sea helps clarify its meaning and relevance in biological and environmental sciences.
