The correct answer is B) people were left with time to do other jobs.

A division of labor occurred when people started to produce a surplus of food because people were left with time to do other jobs.

One of the changes in labor happened when farmers started to produce more than enough food to feed people and trade the excedents. Farmers learned new agriculture techniques and they started to need fewer workers in the farms. These people found other activities to do. They diversified the work or did something different that with time, create value to others. People try new things that were needed to others, diversifying the work, the tasks,  and necessities of people.
