Which of the following is the stage in an investigating when forensic images are obtained?

Acquisition is the correct stage because it's when forensic images (exact copies of digital evidence) are created. This ensures the original evidence remains untouched and admissible in court. Preservation is a broader concept that encompasses maintaining the integrity of evidence throughout the entire investigation, not just the imaging process. Reporting is the final stage where findings are documented and presented. E-discovery is a legal process for identifying and producing electronic information in litigation, which may involve acquisition but is not a stage within a forensic investigation itself.
