The correct answer is B. evergreen dense forests, rubber trees, groundnuts.
Equatorial regions are characterized by warm temperatures and high rainfall. This climate is ideal for the growth of many different types of plants, including evergreen dense forests, rubber trees, and groundnuts.
Evergreen dense forests are found in equatorial regions around the world. These forests are home to a wide variety of plants and animals. The trees in these forests are typically evergreen, meaning they keep their leaves all year round. This is because the climate in equatorial regions is warm and wet all year round.
Rubber trees are also found in equatorial regions. These trees are important because they produce rubber. Rubber is a natural material that is used to make a variety of products, including tires, shoes, and gloves.
Groundnuts are another important crop that is grown in equatorial regions. Groundnuts are a type of legume that is used to make a variety of products, including peanut butter, peanut oil, and peanut flour.
The other options are incorrect because they do not include plants that are typically grown in equatorial regions. Option A includes wheat, barley, and maize. These crops are typically grown in temperate regions, which have cooler temperatures and less rainfall than equatorial regions. Option C includes groundnuts, soyabeans, and potatoes. These crops are also typically grown in temperate regions. Option D includes evergreen coniferous forests, oats, and cocoa. Evergreen coniferous forests are found in cold, dry climates. Oats and cocoa are also typically grown in temperate regions.
