The correct answer is D. Karnataka is a major producer of all of the above horticultural crops.

Mangoes are the most popular fruit in India, and Karnataka is the largest producer of mangoes in the country. The state produces over 10 million tonnes of mangoes each year, which is about 25% of India’s total mango production. The main mango varieties grown in Karnataka are Alphonso, Totapuri, and Neelam.

Grapes are another important horticultural crop in Karnataka. The state produces over 2 million tonnes of grapes each year, which is about 15% of India’s total grape production. The main grape varieties grown in Karnataka are Thompson Seedless, Bangalore Blue, and Black Queen.

Pomegranates are a relatively new horticultural crop in Karnataka, but the state has quickly become one of the leading producers of pomegranates in India. The state produces over 1 million tonnes of pomegranates each year, which is about 20% of India’s total pomegranate production. The main pomegranate variety grown in Karnataka is the Arka Adarsh variety.

Karnataka’s favorable climate and soil conditions make it an ideal location for growing a variety of horticultural crops. The state’s well-developed infrastructure and efficient transportation system also make it easy to export its horticultural products to other parts of India and the world.
