Which of the following groups of crops will thrive in areas with high rainfall?

The group of crops that will thrive in areas with high rainfall is Guinea corn, cowpea, and maize. This is because these crops are well adapted to the tropical climate, and can withstand the high humidity and rainfall associated with such areas. Additionally, they require high moisture content for good germination and growth. Cotton, cowpea, and groundnut, on the other hand, are crops that thrive better in semi-arid areas, where there is less rainfall. Millet, maize, and cotton can also be grown in areas with low to moderate rainfall, but may not do well in areas with high rainfall due to increased risk of fungal diseases and waterlogging. Cocoa, oil palm, and rubber are tree crops that are grown in areas with high rainfall, but they require specific conditions such as well-drained soils and specific climatic conditions to thrive.
