Answer:
The correct answer would be option D, Unlimited Personal Liability.
Explanation:
When a person sets up a new business on his own, without having any other person's involvement, or without any partnership, then he is solely responsible for all the profits he earns and all the losses he bears. He is completely responsible for all the liabilities, which is no doubt not a major advantage of being a sole proprietor. He has the full control over the business, he is the only decision maker, he also enjoys the profits solely, but besides all of these advantages, when it comes to debts or any damages, he is the one solely responsible for these debts and damages. This means he has the unlimited personal liability.
