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

The Arabian Peninsula comprises Saudi Arabia, Yemen, Oman, the United Arab Emirates, Qatar, Bahrain and Kuwait. Jordan is geographically located to the north of the Arabian Peninsula, in the Levant region of West Asia, bordering Saudi Arabia, Syria, Iraq and Israel. Although Jordan shares cultural and historical ties with the Arab world, it is not part of the Arabian Peninsula proper. Kuwait, Oman and Yemen are all peninsular states. Hence Jordan is the correct answer.
