What minimum number of hours did Napoleon reportedly sleep?

• A. four hours
• B. two hours
• C. six hours
• D. eight hours

Answer: (A)

Napoleon is famous for a very tight, disciplined schedule with surprisingly little sleep. In many biographies, the amount of sleep he reportedly needed at night is given as about four hours, sometimes followed by a short nap during the day. This makes four hours the smallest figure that's commonly attributed to him, which is why it’s the best choice for the question. Eight hours would go against the well-known account of his busy, relentless routine, and six hours is simply longer than the typical claim. While a few sources do mention even less sleep, four hours is the most widely cited minimum in standard historical summaries, so it fits the prompt as the minimum.
