In India, highest productivity (kg/ha) of bajra is in the state of:

Correct option is B

Based on recent agricultural data from India, the highest productivity (kg/ha or yield) of bajra (pearl millet) is typically in the state of: 

(b) Haryana 

While Rajasthan is the largest producer of bajra (highest total production) due to its vast area under cultivation, Haryana often has the highest productivity (yield per hectare) due to better irrigation, higher use of improved seeds/hybrid varieties, and better management practices compared to the rainfed cultivation prevalent in other major producing states. 

• Haryana has frequently recorded higher per-hectare yields (e.g., above 2,000–2,300 kg/ha in recent years) compared to Rajasthan, which usually has lower average productivity due to its arid, rainfed climate.
