Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules.

C seems like the answer because at the end of South America, there's nothing blocking the two oceans there from connecting. All of the oceans are connected together. They're just different because of where they are and the conditions of that area of earth.
