Answer:
C. the good a person can do by being a positive acting force
Step-by-step explanation:
The philosophy of inaction promoted the idea that a society will reach its harmony if all people just conform normative order within society. It discouraged people to create some sort of action that disrupted that norms. Which is why it's called "philosophy of inaction"
But a problem arise when the social norms itself is very problematic. Under that situation, completely conforming to that norm will keep a certain group of people felt miserable without ever experiencing a change.
For example, Treating peasants like the were lower human being was considered normal. Because it is a norm in most societies to obey the nobles like they were some sort of higher human beings. If people did not act to make a change and all people followed Lao Tzu's philosophy, this situation will probably still exist today.
