Articles of partnership establish

a) how businesses can raise capital.

b) what business taxes are paid.

c) how profits and losses are divided.

d) what is included in a charter.

The correct answer is c) how profits and losses are divided.

This is done in order to split the profits according to each partner's contribution, as well as to prevent people from suffering in case that a single partner makes a mistake. For example, if a company fails because of a single partner, the people to whom money is owed can only legally attack that single partner because it wasn't the fault of the other partners too.
