Who is defined as a person with a key interest in the success of a business?

The correct answer is defined as a stakeholder. A stakeholder is anyone who has a vested interest in the success of a business. This can include not just employees and shareholders but also customers, suppliers, the community, and even the government. Stakeholders are crucial because their interests can influence business decisions and policies. For instance, shareholders are concerned about profitability and returns on their investments, while employees focus on job security and work conditions.

Understanding the diverse range of stakeholders highlights why the success of a business impacts various groups differently and emphasizes the importance of considering their perspectives when making decisions. This multifaceted interest in a business's success is what solidifies the definition of a stakeholder.
