New Farming Techniques Now Use Unmanned Aerial Vehicles (UAVs) to Create

New farming techniques now use unmanned aerial vehicles (UAVs) to create precise maps of farms and ensure optimal application of fertilizers and watering of crops. This allows farmers to ensure their crops are healthy and increases crop yield. This scenario illustrates:

A) a technological innovation that shifts the production function up.
B) capital accumulation, which causes a movement to the right along the same production function.
C) an increase in the capital stock, which leads to an upward shift of the production function.
D) a technological innovation that causes a movement to the right along the same production function.
