Which one among the following countries is NOT a part of the Arabian Peninsula?

The Arabian Peninsula is the world's largest peninsula, located in Western Asia between the Red Sea and the Persian Gulf. It consists of seven sovereign nations: Saudi Arabia, Yemen, Oman, the United Arab Emirates, Bahrain, Qatar, and Kuwait. Kuwait is situated at the northern tip of the peninsula, while Oman and Yemen occupy the southeastern and southern regions respectively. Libya, however, is located in North Africa and is not part of the Arabian Peninsula. While Libya is an Arab-majority nation and a member of the Arab League, it is geographically separated from the peninsula by the Red Sea and the African continent. The peninsula's boundaries are defined by the Red Sea to the west, the Gulf of Aden and Arabian Sea to the south, and the Persian Gulf to the east.
