Before Bob rented the apartment, he filled out a ().

• A. Form
• B. Lease
• C. Contract
• D. Application

Answer: (A)

The sentence is testing your sense of what kind of document you complete before moving into a rental. When you say someone “filled out a form,” you’re talking about the blank document that collects information (name, contact details, income, references, etc.) and you complete its fields. A lease or contract is the actual agreement you sign later, not something you fill out beforehand. While an application could describe a similar idea, the natural phrasing here is “filled out a form,” making form the best fit.
