Final answer:
Cassie risks losing ownership and control of her app in a corporation, where investors can buy shares and potentially gain control over business decisions. Corporations are separate legal entities, which can raise capital but also dilute ownership.
Step-by-step explanation:
Among the different business structures, Cassie risks losing ownership of her app and control over the business in a corporation. A sole proprietorship is a business owned by one individual who has full control and bears all the risks, including unlimited liability. In a partnership, two or more people share ownership, but control can still be influenced by all partners. However, with a corporation, ownership is divided into shares of stock, which can be bought by investors. This could lead to a loss of control if enough shares are acquired by others. Moreover, if the corporation issues more stock to raise capital, Cassie's ownership percentage could be diluted.
In the case of a limited partnership, it could also be possible to lose control, particularly if Cassie were to take on the role of a limited partner; however, general partners usually retain control over the business. The main defining characteristic of a corporation that differentiates it from the other business structures is that it is a separate legal entity, which can enter into contracts, own assets, and be held legally liable independently of its owners.
If Cassie hopes to maximize personal control over her app and business decisions, then sole proprietorship or partnership may be more suitable. However, for protecting personal assets and potentially raising significant capital, a corporation might be the way to go, with the understanding there's a risk of losing control if too much stock is sold.
