Which statement is true redo log files during instance recovery?

During instance recovery, Oracle performs a 'roll forward' operation where it applies all redo log entries from the online redo log files starting from the last successful checkpoint position. This ensures that all committed changes, and even uncommitted changes, are restored to the data files, bringing the database to a consistent state from the point of failure.

While current and active logs are used, the statement is not as precise as option A regarding starting from the checkpoint position to apply changes.

Inactive redo logs are already archived and are typically not directly required for instance recovery; instance recovery primarily relies on the online redo logs.

Archived redo logs are used for media recovery (restoring from backups), not for instance recovery which uses online redo logs to roll forward changes since the last checkpoint.
