Which term refers to the skills needed by an entrepreneur for success?

The term that refers to the skills needed by an entrepreneur for success is "Enterprise." This concept encompasses the ability to innovate, take risks, and identify opportunities in the market, which are crucial for establishing and growing a business. Successful entrepreneurs demonstrate enterprise by combining their skills and resources to create value, develop new products or services, and adapt to changing business environments.

In contrast, the other options represent different aspects of business but do not specifically capture the entrepreneurial skill set. Investment pertains to allocating resources, usually financial, into ventures but doesn’t reflect the personal attributes or skills that contribute to an entrepreneur's success. Management refers to the organization and coordination of business activities but does not inherently include the creative and risk-taking elements unique to entrepreneurship. Labor refers to the workforce involved in production, but again, it does not denote the entrepreneurial abilities that drive success in business ventures.
