Consider the following statements: I. Maharashtra has the highest acreage under jawar in India. II. Gujarat is the largest producer of groundnut in India. III. Rajasthan has the largest area of cultivable wastelands in India. IV. Andhra Pradesh has the highest per hectare yield of maize in India. Which of these statements are correct?

The correct answer is B because statements II and III are factual according to official agricultural and land use records. Statement II is correct as Gujarat consistently remains the leading producer of groundnut in India due to its favorable agro-climatic conditions. Statement III is correct because Rajasthan possesses the largest extent of cultivable wasteland in the country, largely owing to its arid climate and the presence of the Thar Desert. Statement I is incorrect because, while Maharashtra was historically the leader, recent data often shows Karnataka or a shifting trend in sorghum acreage. Statement IV is incorrect because states like Tamil Nadu or Telangana typically record higher per hectare yields for maize than Andhra Pradesh. Therefore, only statements II and III are robustly accurate.
