Correct Answer:
A. Turkmenistan
This question tests knowledge of world capitals. Ashgabat is the capital and largest city of Turkmenistan, a Central Asian nation. The city is notable for its extensive use of white marble in its architecture, earning it a Guinness World Record for the highest concentration of white marble buildings. It serves as the country's political, economic, and cultural center.
- Armenia: Its capital is Yerevan.
- Azerbaijan: Its capital is Baku.
- Bosnia: The capital of Bosnia and Herzegovina is Sarajevo.
Each distractor is a country with its own distinct capital city, none of which is Ashgabat.
