Hint: Bajra is a well-adapted summer annual crop as double cropping and rotation. India is the largest producer and the highest-producing state in India is Rajasthan.

Complete answer:
> Option A is incorrect. Wheat (Triticum aestivum), also known as bread wheat, is a cultivated species of wheat and the main Indian cereal crop. Approximately 95% of worldwide produced wheat is popular wheat. It is the most commonly grown of all crops and the most monetarily produced cereal. During the major portion of the growing season, the best wheat is produced in areas favored by cool, moist weather followed by dry, warm weather to allow the grain to ripen properly.

> Option B is correct. The most widely grown form of millet is Pearl millet (Pennisetum glaucum). It has been cultivated since prehistoric times in Africa and the Indian subcontinent. Pearl millet is well suited to grow areas with drought, low fertility in the soil, and high temperatures. It performs well in high salinity or low pH soils. "Kambu" is the Tamil name of pearl millet, and is an important food in Tamil Nadu's Indian state.

> Option C is incorrect. Zea mays is an annual plant that is erect, robust, and typically unbranched. It is almost exclusively used for animal feeding, like grain or fodder. In many parts of the world, maize has become a staple food, with overall maize production exceeding that of wheat or rice. It is widely cultivated all over the world, and each year a greater weight of maize is produced than any other crop.

> Option D is incorrect. Sorghum vulgare is a genus of flowering plants in the Poaceae family of grasses, containing about 25 species. Some of these species have evolved as human-consuming cereals and others in livestock pastures. One species is grown for food, while many others are used as plants for fodder, either cultivated worldwide in warm climates or naturalized in pasture lands. It is a major crop worldwide, used for food (as grain and in sorghum syrup or "sorghum molasses"), animal feed, alcoholic beverage processing, and biofuels.

Hence, The correct answer is option (B).

Note: Bajra is cultivated in northern India as a Kharif season crop, but it can be grown as a summer crop in southern India with irrigation. It can be grown in areas where other cereal crops, such as maize or wheat, will not thrive, due to its resistance to difficult growing conditions.
