Which of these is a quality shown by a successful workplace communicator?

A) keeping new information about your field to yourself
B) prioritizing your own needs
C) displaying emotional intelligence
D) sharing proprietary information openly

Displaying emotional intelligence is a quality shown by a successful workplace communicator because it involves being aware of one's own emotions and the emotions of others, discerning between different emotions and labeling them appropriately, using emotional information to guide thinking and behavior, and managing emotions effectively. These skills are important for establishing trust, building relationships, resolving conflicts, and fostering collaboration in the workplace. A, B, and D are not qualities of successful workplace communicators as they involve either withholding or prioritizing one's own interests over those of others, or violating ethical and legal standards by sharing confidential information.
