Which of the following cannot be entered into the Security File?

The correct answer identifies that a cashier's check cannot be entered into the Security File. This is due to the nature of what typically constitutes a Security File. A Security File is primarily meant to hold sensitive information that requires safeguarding, such as personally identifiable information or financial details connected directly to security or identification statuses.

A cashier's check is a negotiable instrument that represents a sum of money and is used for transactions, but it does not serve as a method for verifying an individual's identity or secure access. In contrast, money orders, credit card information, and personal identification numbers are directly related to individual financial or personal security and can be included in security-related files for various purposes, such as fraud prevention or identification verification.

Understanding this distinction clarifies that items intended for direct monetary transactions, like a cashier's check, do not fit the functional role of what is typically stored within a Security File.
