Final answer:
D. The four field rotation in agriculture during the Industrial Revolution resulted in increased yields and more efficient land use, leading to enhanced soil fertility and overall sustainability in farming.
Step-by-step explanation:
D. The introduction of the "four field rotation" system during the Industrial Revolution allowed European farmers to use their land more efficiently, which contributed to greater agricultural yields and an increased efficiency in food production.
This rotation method improved soil fertility without leaving a significant portion of the land fallow, breaking from the traditional three-field system. Crops like turnips and clover were introduced to replenish soil nutrients, resulting in more sustainable farming practices that supported the growing population of the time.
