What are the four political capitals of Arabia in order?

The correct sequence of the four political capitals of Arabia is Riyadh, Muscat, Doha, and Abu Dhabi. Riyadh is the capital of Saudi Arabia, which plays a central role in the Arabian Peninsula. Muscat serves as the capital of Oman, situated at the southeastern corner of the peninsula, while Doha is the capital of Qatar, known for its rapid modernization and growing influence in the region. Finally, Abu Dhabi is the capital of the United Arab Emirates (UAE) and is a key political and economic center.

The other options provided do not represent capitals within Arabia itself. Option B lists Damascus, Baghdad, Cairo, and Constantinople, which are capitals of countries in the broader Middle Eastern region but not specifically part of Arabia. Thus, while they are significant cities, they do not meet the criteria for the capitals of Arabia.
