Final answer:
The city provided in the student's options is not the capital of the Democratic Republic of Congo; the actual capital city is Kinshasa.
Step-by-step explanation:
The name of the city in the Democratic Republic of Congo referred to in the question is not mentioned among the choices provided. However, it is important to note that the modern capital city of the Democratic Republic of the Congo is Kinshasa. The choices Diboondo, Kongo, and Boma do not correspond with the current capital. The Democratic Republic of the Congo was once known as Congo-Leopoldville, then Zaire, and Congo-Brazzaville refers to the capital of the neighboring Republic of the Congo. Over time, this country has experienced significant political changes and a turbulent history, influencing its regional divisions and cities.
