Answer:
Based on the map, the city that appears to have traded almost exclusively by shipping rather than land routes is Mombasa.
Mombasa is located on the eastern coast of Africa, along the Indian Ocean. The map shows a series of dots running from north to south along the coast of the Indian Ocean, indicating cities and trade routes that were connected through maritime trade. Mombasa is one of these cities, and its location on the coast suggests that it relied heavily on sea routes for trade.
In contrast, the other options mentioned - Mwenemutapa, Funj, and Benin - are not specifically shown as being located along the coast or connected to the maritime trade routes on the map. While these kingdoms may have engaged in trade, it appears that their trade was not predominantly reliant on shipping by sea.
Therefore, based on the information provided by the map, Mombasa appears to have traded almost exclusively by shipping rather than land routes.
