Selected Answer: C
Explanation: A rolling update gradually updates instances in a cluster one by one (or in small batches) while keeping the application running. This ensures minimal downtime and allows the administrator to monitor the new version for issues before updating the next instance. ✔ Step-by-step process: Update one VM. Monitor for issues. If stable, update another VM. Repeat until all VMs are updated.
