The correct description of Sudanese culture from the options provided is that "Fava beans are common throughout Sudan."
Sudan has a rich agricultural tradition, and fava beans are indeed a popular food in the country.
The other statements about Catholicism being the main religion and traditional homes being made with concrete are not accurate, as Islam is the predominant religion in Sudan, and traditional homes are often made with mud or thatch rather than concrete. Additionally, bomba drums are significant in certain contexts but are not primarily used to tell current events.
