Into how many macro agricultural regions has Randhawa divided India ?

The correct answer is (a). Randhawa divided India into four macro agricultural regions:

• The Indo-Gangetic Plain: This region is the most important agricultural region in India, accounting for about 40% of the country’s agricultural output. It is characterized by a warm, humid climate and a long growing season. The main crops grown in this region are rice, wheat, sugarcane, and cotton.
• The Deccan Plateau: This region is located in the southern part of India and is characterized by a dry, tropical climate. The main crops grown in this region are millets, sorghum, and pulses.
• The Western Ghats: This mountain range runs along the western coast of India and receives a high amount of rainfall. The main crops grown in this region are coffee, tea, and spices.
• The Eastern Ghats: This mountain range runs along the eastern coast of India and receives a moderate amount of rainfall. The main crops grown in this region are rice, jute, and oilseeds.

The other options are incorrect because they do not represent the number of macro agricultural regions that Randhawa divided India into.
