Answer:
C. Large, deep body of water that contains fresh water
Explanation:
Keywords in question: "Freshwater wetland"
Answer A does not have those keywords in the answer. It does not talk about water, it talks about acidic areas!
Answer B does talk about water, but it's not specifically saying anything about freshwater. It talks more about the landscape of the area feeding water into rivers.
