The correct answer is: a) Pineapple, banana, citrus fruits.
Pineapple, banana, and citrus fruits are all tropical fruits that grow well in the warm, humid climate of Mizoram. They are also popular crops among farmers in the state, as they are relatively easy to grow and can be sold for a good price.
Tea, coffee, and rubber are all plantation crops that are grown in tropical and subtropical climates. However, they are not as well-suited to the climate of Mizoram as pineapple, banana, and citrus fruits. The climate in Mizoram is too wet and humid for tea and coffee, and the soil is not suitable for growing rubber.
Wheat, barley, and sugarcane are all cereal crops that are grown in temperate climates. They are not well-suited to the climate of Mizoram, which is too warm and humid. The soil in Mizoram is also not suitable for growing these crops.
Cotton, jute, and tobacco are all fiber crops that are grown in tropical and subtropical climates. However, they are not as well-suited to the climate of Mizoram as pineapple, banana, and citrus fruits. The climate in Mizoram is too wet and humid for cotton and jute, and the soil is not suitable for growing tobacco.
