B Correct answer
Explanation

Crop rotation involves growing different crops in succession on the same land to prevent nutrient depletion and break pest/disease cycles. This maintains soil fertility naturally. Regular tilling can actually harm soil structure, repeatedly growing the same crop depletes specific nutrients, and irrigation provides water but does not maintain fertility.
