Concept:Mali is a landlocked country, so its exporters depend on seaports of neighbouring coastal countries.
Explanation:Mali has no direct access to the sea, meaning all its exports travel through another country's port.
The port of Abidjan in Côte d'Ivoire has long served as Mali's principal trade outlet.
It handles roughly
70% of Mali's imports and exports, more than any other port.
Although Dakar, Banjul, and Lagos are also accessible, they are less important for Malian trade.
Because Abidjan is historically the leading transit seaport for Mali, its exports are most likely to leave through that port.
Answer:B. Abidjan
