The large body of water in the image above is partially enclosed by land and is larger than a bay. It is best described as an)
A. gulf
B. river
C. estuary
D. strait

The correct answer would be A. gulf.

We can immediately eliminate option B and D, because rivers and straits are normally smaller than bays.

Option C wouldn't make sense either, since an estuary is not an area enclosed by land, but rather an area where streams and rivers flow into a larger body of water, like an ocean.

Ultimately, this gives the correct answer to be A. Gulf.

Let me know if this helps!
