The correct answer is Electronic discovery.

This term describes the formal legal process of identifying, collecting, preserving and producing electronically stored information so it can be presented as evidence in a criminal trial. The process covers preservation to prevent alteration, documented collection and imaging to maintain integrity, review for relevance and privilege, and production for use in court.

Repudiation is incorrect because repudiation refers to a party denying an action or transaction and is not a process for gathering or protecting electronic evidence. It relates to the concept of non repudiation rather than to evidence collection.

Cloud Audit Logs is incorrect because audit logs are a type of record that can be used as evidence but they are a tool or data source rather than the legal process of identifying and producing evidence. Logs may be collected during electronic discovery but the logs alone do not constitute the end to end e discovery process.

Chain of custody is incorrect as the best answer because chain of custody refers specifically to the documentation that tracks who handled evidence and when to preserve its integrity. The chain of custody is an important part of evidence handling and it is often required during electronic discovery, but it does not by itself describe the full process of identifying collecting preserving and producing electronic records.
