The correct option is B Both the assertion and reason are true but the reason is not the correct explanation of the assertion.
Among the sixteen essential plant nutrients, nitrogen, phosphorus and potassium are the most common nutrients found deficient in Indian soil. Supply of these nutrients to the soil through biofertilizers (microbes which enhance soil nutrients is necessary to keep the soil rich in plant nutrients for achieving maximum yield. Irrigation practices are also helpful in enhancing the crop yield. In this way, both biofertilizers and irrigation are equally important for high crop yield. However, irrigation and the use of biofertiliers are independent of each other and hence both the assertion and reason are true but the reason does not explain the assertion.
