In disaster recovery, how do hot backups differ from cold backups?

Explanation:
The main idea here is how ready a backup is to take over after a failure. Hot backups are kept online as live replicas that run in parallel with production, so you can fail over quickly with minimal downtime. Cold backups, on the other hand, are offline and need to be restored before they can take over, which means a slower recovery. So the correct description is that hot backups are live replicas for quick failover, while cold backups are offline and slower to recover. The other options mix up online/offline status or the speed of recovery, which doesn’t match how hot versus cold backups actually function in disaster recovery.
