Explanation:

All the given crops - groundnut, sesamum, and pearl millet are predominantly rainfed crops in India. Rainfed agriculture refers to the practice of growing crops entirely on rainfall, without any irrigation or minimal irrigation support.

In India, around 60% of the net sown area is rainfed, and it contributes to about 40% of the total food grain production. Groundnut, Sesamum, and Pearl Millet are some of the important rainfed crops grown in different parts of the country. These crops are usually grown in areas where rainfall is adequate and irrigation facilities are scarce or absent.
