The Mediterranean Sea is the body of water that separates Europe, Africa, and Asia. So let`s analyze the options.
Option 1: Jordan and Iraq do not have any coastline with the Mediterranean Sea, while Lebanon does. Hence this is incorrect.
Option 2: Iraq doesn`t border the Mediterranean Sea but Lebanon does. So, this too is incorrect.
Option 3: Lebanon and Syria both have coastlines on the Mediterranean Sea and hence this is correct.
Option 4: Jordan doesn`t have a Mediterranean coastline, while Lebanon and Syria do. This makes it incorrect.
So, the correct answer is option 3, which includes only Lebanon and Syria, both Mediterranean-bordering countries.
