Answer:
D) understand and deal with his or her own emotions.
Step-by-step explanation:
Emotional intelligence refers to the ability to understand and manage one's own emotions, as well as the emotions of others. While emotional intelligence can certainly help individuals navigate social situations and influence others, it is not about using emotions to manipulate or engage in counterproductive behavior. Instead, individuals with high emotional intelligence are often able to regulate their own emotions, empathize with others, and communicate effectively, which can lead to positive outcomes both personally and professionally. Therefore, option D is the correct answer.
