Answer:
Arrow B is pointing to the Mediterranean Sea.
Step-by-step explanation:
On the map, we have most of Africa as the focal point, with four arrows pointing outward of the continent and pointing toward water bodies. Arrow A is pointing to the Atlantic Ocean, arrow B is pointing to the Mediterranean Sea, arrow C is pointing to the Red Sea, and arrow D is pointing to the Gulf of Aden.
The Mediterranean Sea is a sea that is a natural boundary between Africa and Europe, as well as a little part of Asia. It is a relatively warm sea that also has a very big depth, and the big depth comes from the subduction zone formed by the collision of the African and Eurasian plates. This sea has huge economic and geopolitical importance, not just to the people living around it, but globally.
