After promising Maria that you will look into the issue and get back to her. Later in the day, you escalate the pay gap issue to your manager, Sarah, the Accounting Director, in her office. Sarah told you: "I hired Marica almost five years ago when I was the Accounting Manager. She was given a competitive salary. The previous manager hired Ron while I was on maternity leave. Maria is one of the smartest women I know. She is a hard worker with genuine integrity. She should have an equivalent salary based on her character alone. I suggest that you talk with Nicole from HR".
As you reflect on your conversation with Sarah, you realize that she must follow which ethical framework?

a. Principle, universal, or rights based ethics
b. Virtue ethics
c. Utilitarian ethics
