Answer: A) Gaza
Step-by-step explanation:
A) Gaza is not a city of culture and trade in Sub-Saharan Africa.
Gaza is actually a city located in the Gaza Strip, a small Palestinian territory in the Middle East. It is not part of Sub-Saharan Africa.
On the other hand, Dakar, Lagos, and Johannesburg are all cities in Sub-Saharan Africa that are known for their rich cultural heritage and thriving trade industries.
