This statement is false. In fact, it is the exact opposite of the truth.
Limited liability is not an advantage enjoyed by partnerships and sole proprietorships. In fact, limited liability is a major reason for a person to incorporate rather than to do business as a sole proprietor. In sole proprietorships and partnerships, the owners of the firm are completely liable for any debts incurred by the firm. There is no legal distinction between the person and the business. The person's assets can be taken to pay for the firm's debts.
This statement is false, then, because limited liability is an advantage of incorporation, not of the other types of ownership mentioned here.
