What is the role of a colleague?

The correct choice accurately defines a colleague as a person you work with. In a professional context, colleagues are individuals who share a workplace, are engaged in similar tasks, or collaborate on projects and responsibilities. This relationship can foster teamwork, collaboration, and communication within the work environment.

While socializing outside of work (as mentioned in another choice) can provide a deeper connection between individuals, it is not a defining characteristic of a colleague. Similarly, friendships from childhood or relationships with family members do not inherently involve a professional context, which is essential for identifying someone as a colleague. The term specifically implies a work-related partnership or association, distinguishing it clearly from other types of relationships.
