During an investigation, what is allowed regarding documents obtained from the investigated person?

The option indicating that copies can be made and retained for investigation purposes is correct because, during an investigation, it is essential to maintain the integrity of the evidence while also ensuring that the investigation can proceed effectively. Creating copies allows the investigating body to analyze and reference the information contained in the documents without compromising the originals. This practice helps prevent any loss or damage to crucial evidence that may be needed for legal proceedings or further investigation.

Maintaining copies as part of the investigation documentation process ensures that all relevant information is preserved adequately, allowing for a thorough examination and review. This is particularly important in scenarios where the originals might have to be returned to the individual who provided them after the investigation is complete. Additionally, copies can be shared with other stakeholders involved in the investigation while protecting the original documents.
