Step-by-step explanation:
The correct answer to the question is d. principal-agent.
In an employer-employee relationship, a principal-agent relationship is formed when the employer hires an employee and gives them the authority to act and enter into contracts on their behalf. The employer is the principal who delegates authority, and the employee is the agent who acts on behalf of the employer.
