Correct answer & explanation
✓
Create a change set that replaces the resource causing the limit error with a smaller instance type.
Creating a change set that replaces the resource causing the limit error with a smaller instance type allows the update to proceed without manual intervention, minimizing downtime. Option A is wrong because manually modifying the resource can cause stack drift and may not be safe. Option C is wrong because rolling back does not resolve the underlying resource limit issue. Option D is wrong because deleting and recreating the stack would cause significant downtime.
