Which documents are considered part of normal business documents?

The correct answer is that rental agreements, mortgages, and driver's licenses are indeed considered part of normal business documents because they are essential for establishing identity, proving residency, and facilitating various transactions. These documents serve as backgrounds for numerous business dealings, including renting property and securing loans, making them fundamental to a wide range of professional and personal relationships.

Rental agreements and mortgages are critical in real estate transactions, defining the terms of property usage and ownership. Driver's licenses not only serve as identification but are also frequently required for various contractual engagements, including those involving financial institutions and business services.

Checks and credit cards, on the other hand, are more transactional tools rather than documents that provide context or identity related to businesses. While passports and identification cards have their place, they don't typically fall under the category of documents routinely utilized in business operations to the same extent as rental agreements and mortgages. Similarly, social security cards and student IDs have specific uses and are not broadly applicable within business contexts outside of identification verification.
