c.sometimes clear.
Explanation:
Human resources involves handling the manpower of an organisation in such a way that productivity and motivation to perform are always high and aimed at meeting organisational goals.
While dealing with employees and applicants, the legality of actions are sometimes unclear because depending on the situation one could be taking a wrong or right action.
For example Sharon as the Human Resources Director has an ethical duty to pursue the well being of the staff, and when there is a life threatening practice in the workplace she should take actions to remove it. The problem arises when management is aware of the practice and is in support. Sharon also has an obligation to her employer.
