Correct answer & explanation
✓

It minimizes downtime by using a rolling update and preserves data by detaching and reattaching existing EBS volumes. Option A is wrong because it does not preserve existing EBS volumes, leading to data loss. Option C is wrong because terminating all instances causes downtime and does not preserve data. Option D is wrong because patching running instances may cause application instability and does not ensure data preservation in case of rollback.
