Empirical data is not a source for people acquiring social knowledge
Answer: Option B
Explanation:
People acquire social knowledge based on their interaction with the outside world. It could be in the form of individuals, groups or organizations. These three sources strive to serve as information hubs for people who tend to acquire social knowledge.
However empirical data is not a source for interaction with the outside world as this data is collected by mere experience by people with the outside world. This information is not obtained through pure logic.
