The correct answer is:
b. Farmers can store more food due to their sedentary nature and diet.
Farmers typically produce surplus food, particularly grains and other crops, which they can store for longer periods of time. In contrast, nomads have a more mobile lifestyle and often rely on hunting, gathering, or herding, which limits their ability to store food for extended periods. While nomads may have some methods to preserve certain types of food, they generally cannot accumulate and store food to the same extent as farmers.
