Which term signifies the "expectations and limits" associated with a particular task or profession?

The term that signifies the "expectations and limits" associated with a particular task or profession is "role." In the context of a job or profession, a role defines the responsibilities and duties that an individual is expected to fulfill. This includes the standards of conduct and performance that are associated with that position, guiding how one should act in different situations within the workplace.

In contrast, the other options do not capture the concept of expectations and limits associated with a profession effectively. The first option refers to risk factors related to health and disease, which focuses on individual attributes rather than the framework of duties in a role. The third option describes privacy, which does not pertain to professional expectations or job responsibilities. The fourth option addresses safety, which is related but does not specifically convey the idea of defined roles and responsibilities. Therefore, "role" best embodies the concept of expectations and limits in a professional context.
