Among the options you provided, the most fitting choice related to notable kingdoms in Africa is "Merde," assuming you meant "Mali." The Mali Empire was a significant historical kingdom in West Africa, known for its wealth, particularly in gold, and its cultural achievements, including the famous city of Timbuktu.
The other options (Han, China, and Kushan) refer to Chinese and Indian empires, not African kingdoms. However, it is worth noting that the Kingdom of Kush (often confused with "Kushan") was indeed a prominent kingdom located in present-day Sudan, which is part of Africa.
