One way to track the activity that is occurring in a system is:

• A. A Gantt chart.
• B. A Data backup.
• C. Biometrics.
• D. An Audit trail.

Answer: (D)

An audit trail records who did what, when, and on which data, creating a verifiable history of system activity. This allows accountability, security monitoring, and forensic investigations, and it supports compliance with privacy and data protection requirements. When a clinician accesses or alters a patient record, the audit trail captures the user ID, timestamp, action, and data touched, so investigators can reconstruct events and identify anomalies. Other options serve different purposes: a Gantt chart is used to plan and track project timelines, a data backup is prepared for data recovery after loss, and biometrics are methods for authenticating identity rather than logging ongoing actions.
