The correct answer is C. proprietorship.
A proprietorship is a business owned and operated by one individual. It is the simplest and most common form of business ownership. Proprietorships are easy to form and have few government regulations. However, they also have some disadvantages, such as unlimited personal liability and difficulty raising capital.
A private corporation is a business owned by a group of shareholders. It is more complex to form than a proprietorship and is subject to more government regulations. However, it also offers some advantages, such as limited liability and the ability to raise capital more easily.
A personal business is a business that is not incorporated. It can be a proprietorship, partnership, or corporation. Personal businesses are not subject to the same government regulations as corporations, but they also do not have the same protections.
In conclusion, the correct answer is C. proprietorship. A proprietorship is a business owned and operated by one individual. It is the simplest and most common form of business ownership. Proprietorships are easy to form and have few government regulations. However, they also have some disadvantages, such as unlimited personal liability and difficulty raising capital.
