Question

this water body separates the atlantic ocean and the mediterranean sea. (it also separates the continents of europe and africa) options: english channel, straight of gibraltar, danube river, baltic sea

Explanation:

The description says the water body separates the Atlantic Ocean and the Mediterranean Sea, and also Europe and Africa. The Strait of Gibraltar is the water body that does this. The English Channel separates England and France, the Danube River is a river in Europe, and the Baltic Sea is a sea in Northern Europe, so they don't match the description.

Answer:

B. Straight of Gibraltar
