Selected Answer: C
Option B is incorrect because Change Sets allow you to see how your proposed changes might impact your running resources before implementing them, it will not prevent the error when deleting the stack. Option D is incorrect because Drift Detection identifies stack resources whose actual configuration differs from their template, it does not allow the SG to be retained when deleting the stack. Option A works, but is extremely inefficient. Option C is correct. E.G. using the CLI command $ aws cloudformation delete-stack --stack-name my-stack --retain-resources mysg1 https://repost.aws/knowledge-center/cloudformation-stack-delete-failed
