Concept:Agricultural marketing in West Africa is affected by problems linked to uneven supply, movement of goods, and lack of finance.
Explanation:I. Seasonality of produce is a problem because production is not uniform throughout the year.
This causes gluts and shortages, leading to unstable prices and incomes for farmers.
II. Transportation of produce is a problem because roads are often poor and transport costs are high.
Farm produce is also perishable, so delays during transport lead to losses.
III. Access to credit is a problem because farmers and marketers lack funds for storage, processing, and transportation.
Without credit, they cannot market their produce effectively.
All three listed items are genuine problems in West African agricultural marketing.
Answer:D. I, II and III
