Answer: d. founder: second-stage entrepreneur
Step-by-step explanation:
The founder is the person who initiates the business therefore John in this scenario is the founder of the business.
A second-stage entrepreneur is the person who takes over the business after the company leaves its initial startup phase. As Larry now runs the business even though John founded it, Larry would rightly be classified as a second-stage entrepreneur as he runs the business after the startup phase where John founded it.
