Which feature allows administrators to track all changes made to records?

Correct answer: Field History

Field History Tracking (Option C) in Salesforce allows administrators to enable tracking on specific fields of an object so that every change to those field values, including who made the change, when it was made, and what the old and new values were, is recorded and viewable on the record. Option A (Audit Trail) refers to the Setup Audit Trail, which tracks administrator configuration changes in Setup rather than data-level record changes. Option B (Activity History) stores a log of completed tasks and events related to a record, not changes to record field values. Option D (Change Log) is not a standard Salesforce feature name and does not correspond to a native Salesforce capability for tracking record changes.
