The correct answer is (d) Uttar Pradesh.
Uttar Pradesh is the largest producer of tobacco in India, accounting for more than one-third of the country’s total production. The state has a long history of tobacco cultivation, and tobacco is grown in a variety of agro-climatic zones. The main tobacco-growing districts in Uttar Pradesh are Mirzapur, Jaunpur, Sultanpur, Pratapgarh, and Rae Bareli.
Tobacco is an important cash crop for farmers in Uttar Pradesh, and it provides employment to a large number of people. However, tobacco cultivation is also a major source of air and water pollution, and it is a major risk factor for cancer and other diseases.
The other options are incorrect. Andhra Pradesh is the second largest producer of tobacco in India, followed by Gujarat and Karnataka. However, none of these states produce more than one-third of the country’s total tobacco production.
