An entrepreneur is:

An entrepreneur is a person who organizes and then runs a business. This definition captures the essence of entrepreneurship, which involves not only the initiation of a business venture but also the management and oversight of its operations. Entrepreneurs take on financial risks in hopes of profit and innovation, often bringing new ideas or services to the market. This role requires a combination of creativity, leadership, and business acumen.

In contrast, the other options refer to specific professions or roles that do not encompass the full scope of what an entrepreneur does. For instance, a French teacher focuses on education and language instruction, a government employee works within public sector frameworks, and a member of the military serves in defense roles. While all these professions are important, they lack the entrepreneurial aspects of risk-taking, business operation, and innovation found in option B.
