Explanation:

An entrepreneur is defined as someone who starts and runs their own business. "Worked for a small business" describes an employee, "controlled the market for a product" describes a monopolist or market controller, and "gave money to help people in need" describes a philanthropist. John D. Rockefeller started his own business (Standard Oil), so the correct option is the one stating "started his own business."
