    The correct answer is B) Rob should clean the bathroom and Jenni should change the car's oil.

    Explanation:

    The specialization and division of labor has enabled greater efficiency in economic development worldwide mainly since the industrial revolution.

    The situation of Jenni and Rob is an example about earning time and resources through the specialization.

    In an 8-hour workday Jenni could charge oil in 48 cars and Rob could clean 48 bathrooms. If the roles were reversed Jenni only could charge oil in 24 cars and Rob could clean 24 bathrooms.

    Any other task load combination would have an intermediate efficiency between both ends.
