Corporations differ from partnerships and other forms of business association in two ways. One of these is that:. a. they are regulated by the Federal Trade Commission.
b. they are formed simply by an agreement entered into among their members.
c. they must be publicly registered or in some way officially acknowledged by the law.
d. their shareholders are entitled to their share of the company's profits as soon as they are ascertained or determined.

c. they must be publicly registered or in some way officially acknowledged by the law.

Explanation:

Corporations tend to have many shareholders who would get hurt if the company fails and for this reason they are regulated by the law. They must be publicly registered to allow people to purchase and sell shares and they must have the official acknowledgement of the law.

The formation of a corporation can be complicated and require a relatively high number of legal processes and corporations are not regulated by the Federal Trade Commission.

Also, even though shareholders are technically entitled to the company's profits, they don't get to collect it immediately because the company needs money to function and grow.
