Riley, an engineer at TechWorks, notices a defect that occurs in about $1\%$ of the company$$s products due to a flaw in the lead engineer$$s calculations. Riley is up for a promotion soon and doesn$$t want to risk getting on the lead engineer$$s bad side, but he knows that not speaking up could cause unhappy customers who receive defective products. Riley decides to speak up and communicate with the lead engineer about the problem. As a result of figuring out the problem, he ends up receiving a promotion and a raise anyway. What ethical framework did Riley use to make this decision?

Post$-$modernism, because he rejected the notion that there is always one right answer

Utilitarianism, because this is the action that benefits the most people

Egalitarianism, because this put him and his supervisor on equal footing

Ethical egoism, because he chose the action that would benefit himself the most
