What are the two main purposes that companies use social media ?

D.

Explanation:

Perceived Organizational Support (POS) can be defined as a perception of employees about how much their company cares and values their contribution and well-being. The concept of Perceived Organizational Support evolved from the support theory of Eisenberger and Rhoades.

In simple terms, POS can be referred to an organization's contribution to the socio-emotional needs such as approval and benefits of employees.

The theory of Cognitive Dissonance was originated by Leon Festinger. The theory suggests that situations that beliefs, attitudes, or behaviors that are conflicting inculcate the feelings of mental imbalance. When one's own beliefs, attitudes, and behaviors come in contradiction to each other one will try to learn that and be consistent with that action, belief, etc.

In the given case, Lance has experienced both perceived organizational support and cognitive dissonance. It is because he did not get that much contribution from his organization for his performance as he expected. And learned to work in a University that has no sports.

So, the correct answer is option D.
