c. Gulf of Mexico

Answer 1

the answer is   C - Gulf of Mexico

Answer 2

Mississippi River flows into the Gulf of Mexico - so that's how I know that the correct answer is c!

There is also a Rio Grande that flows into the same Gulf, but there are actually many rivers of this name, as it just means "Big River" in Spanish.
