Concept:Traditional Yoruba economic activities were mainly farming, crafts, and trade, not gathering.
Explanation:The Yoruba people of south-west Nigeria were known for settled agriculture and skilled crafts.
Farming was their major occupation, with crops like yams and cocoa.
Weaving and hairdressing were common specialised trades within Yoruba communities.
Gathering, however, is a feature of hunter-gatherer societies, not the traditional Yoruba economy.
Therefore, gathering does not fit among the listed traditional Yoruba economic activities.
Answer:B. Gathering
