How does a sole proprietorship differ from a partnership or corporation?

A) the owner of a sole proprietorship can arrange for the continuity of the business in his will. A corporation continues without change if a shareholder dies.

B) legally and financially, a sole proprietorship and its owner are a single entity. Partnerships and corporations are entities that are legally seperate from their owners.

C) the owner of a sole proprietorship is liable for financial obligations of the business, but cannot be sued for malpractice. Partners and shareholders are not liable for the business financial obligations.

D) the sole proprietorship owner's liability is limited to the amount of his investment in the business, as is the shareholder. General partners have unlimited liability.
