Which one of the following countries of South-West Asia does not open out to the Mediterranean Sea?

Syria, Lebanon, and Israel are all countries in South-West Asia that have a coastline on the Mediterranean Sea.

Jordan is located inland and does not have access to the Mediterranean Sea. It is bordered by Syria to the north, Iraq to the northeast, Saudi Arabia to the east and south, and Israel and the West Bank to the west.

Hence, Jordan does not open out to the Mediterranean Sea.
