__ is someone who is included on your contract and shares the financial responsibility with you. 1) Landlord 2) Cotenant 3) Cosigner 4] Guardian

The correct answer is:<br /><br />**3) Cosigner**<br /><br />### Explanation:<br />A **cosigner** is someone who agrees to share financial responsibility with you on a contract, such as a lease or loan. They are legally obligated to pay if you fail to meet your financial obligations. This is different from a **cotenant**, who shares the living space and rent but is not necessarily responsible for your portion of the payment unless specified in the agreement. A **landlord** owns the property, and a **guardian** is typically a legal caretaker, which does not apply in this context.
