What is the limitation of sending financial statements via email and USB for comparison?

• A. It guarantees authenticity of the documents.
• B. It ensures version control across recipients.
• C. It does not ensure that the documents were not modified.
• D. It automatically encrypts all content.

Answer: (C)

The main idea here is the lack of integrity verification when transferring documents. Sending financial statements by email or on a USB does not provide a tamper-evident path, so there’s no reliable way to know if the file has been altered since it left the source. Attachments can be replaced, files can be modified in transit, and a USB copy can be edited or substituted without any built-in mechanism to detect it. To ensure that the documents haven’t been changed, you’d need safeguards such as cryptographic hashes or digital signatures, or a secure transfer method that binds the document to its origin and exact content. That’s why the limitation is that it does not ensure the documents were not modified.
