Answer is D. GPS technology has led development of robotic tractors for planting, fertilization, and crop harvesting.
Before advancement of the technology it was difficult for farmers to carry out farm planning, field mapping, soil sampling, tractor guidance, crop scouting, and yield mapping. But with the development of Global Positioning System (GPS), farmers can take informed decision about application of pesticides, herbicides, and fertilizers, and better control to disperse these chemicals. Farmers can use data in reducing expense, better harvesting technique and a higher yield, and creating a more environmentally friendly farm.
