Option A, Emotional contagion
Explanation:
The concept of emotional contamination in one person is the direct activation of similar emotions and actions in others.
Feelings may be conveyed indirectly or directly through individuals in several different ways.
There's also important evidence that people display feelings associated with other people's facial, auditory and postural gestures. If you imitate the body, you will hear what you say. Then, you feel what another person feels.
