The correct answer is: a) Tropical Monsoon.
Assam is a state in northeastern India. It is located in the foothills of the Himalayas and has a tropical monsoon climate. The climate is characterized by hot, humid summers and cool, dry winters. The monsoon rains are essential for agriculture in the state.
Arid climates are characterized by low rainfall and high temperatures. They are found in deserts and semi-deserts around the world. Arid climates are not suitable for agriculture without irrigation.
Semi-arid climates are similar to arid climates, but they receive more rainfall. They are found in steppes and savannas around the world. Semi-arid climates can support some agriculture, but they are not as productive as humid climates.
Mediterranean climates are characterized by warm, dry summers and cool, wet winters. They are found in the Mediterranean region of Europe, North Africa, and the Middle East. Mediterranean climates are ideal for growing grapes and olives.
