Final answer:
Option c, positive impact on personal well-being, is not an aspect of the 'dark side' of entrepreneurship, as it suggests a benefit rather than a risk or challenge associated with entrepreneurship.
Step-by-step explanation:
The dark side of entrepreneurship refers to the potential negative consequences and challenges that can accompany starting and managing a business. Options a, b, and d in the question all represent elements of this dark side. Specifically, ethical dilemmas and moral challenges can arise in situations where entrepreneurs must make decisions that could impact employees, customers, or society. Additionally, excessive risk-taking and impulsivity can potentially harm the business and its stakeholders if not managed properly. Burnout and mental health issues may also emerge due to the high pressure and stress that entrepreneurs often face. In contrast, option c, positive impact on personal well-being, is not considered an aspect of the dark side of entrepreneurship as it reflects a potential benefit rather than a risk or challenge.
