Answer:
I believe the description that best relates to a gulf is:
A. a large area of salt water that is surrounded by land on three sides
Step-by-step explanation:
A gulf is basically an inlet, a part - an "arm" - of the ocean that is almost completely enclosed by land. That means it has land on three sides. On the fourth side, there is an opening that connects that enclosed water, so to speak, to the rest of the ocean. It is as if there was an indentation in the coast that allows the water to come in.
