Phospholipids, 2 layers. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the lipid bilayer with embedded proteins.

I'm thinking maybe it could probably be B
Explanation:
Gas poisoning in our environment is a major problem due to its high incidence. In the specific case of carbon monoxide poisoning, it is the leading cause of death due to involuntary poisoning in our environment, often coexisting with cyanide poisoning. Both poisonings can be serious, based on their diagnosis on the mere suspicion of the doctor. In addition, its importance lies in the fact that both poisonings have a specific treatment. Normo or hyperbaric oxygen therapy is the treatment of choice for carbon monoxide poisoning. In the case of cyanide poisoning, hydroxocobalamin is today the treatment of choice, as it has proven to be an effective antidote.
Here is your answer
Rocks break down as they interact with air and weather - Weathering
Density differences and other factors cause metals to concentrate in igneous rocks - volcanic activity
Seawater heats up from contact with hot rock, metals dissolves in it, the water rises and contacts cooler water, causing metals ores to settle on the ocean floor - hydro thermal energy
