Step 1: Understand the Strait of Gibraltar
It is a narrow strait that connects the Mediterranean Sea to the Atlantic Ocean.
Step 2: Location
It lies between southern Spain and northern Morocco.
Step 3: Other options
- Mediterranean and Red Sea are connected by the Suez Canal, not the strait.
- Red Sea and Persian Gulf are separate bodies of water, connected by different routes.
- Persian Gulf and Arabian Sea are connected through the Gulf of Oman and Arabian Sea, not via the Strait of Gibraltar.
Thus, Option (A) is correct.
