Best Answer Explained in Below-:

Luanda is the capital city of Angola, a nation located on the southwestern coast of Africa. Established as a significant port and trading center, Luanda has played a vital role in Angola's history, particularly during its colonial period under Portuguese rule. The city is known for its rich cultural heritage, lively music scene, and beautiful coastal landscapes.

Angola, which gained independence from Portugal in 1975, is rich in resources, including oil and diamonds, contributing to its economic growth. The capital city reflects the country's diverse history, with a blend of modern development and colonial architecture. The other options presented play prominent roles in their respective nations: Guyana with its capital Georgetown, Liberia with Monrovia, and Armenia with Yerevan. However, none of these countries have Luanda as their capital.

Understanding this context solidifies that option D, Angola, is the correct answer. Recognizing the geographic and political significance of Luanda is crucial in distinguishing it from the capitals of the other countries listed.
