B Correct answer
Explanation

Precision farming is a farming system in which inter and intra-field variability in crops are observed and responded to. The goal of precision farming is using information technology in decision making for optimizing returns on inputs and at the same time preserving resources. Polythene sheets prevent weed and soil pathogens growth. They accelerate the uptake of micronutrients from the soil. They reduce the irrigation water requirement of the crop and thus conserve soil moisture. Thus polythene sheets are used in precision farming.
