Why B? Backup platform always must be available for recovery operations - it's D: "The platform must be available 24 hours a day, 7 days a week with the exception of scheduled downtime".

Selected Answer: A
A and C are non-functional, while B and D are functional. Recoverability is the point: Using change control policies betters the ability to recover in case of failure/defect. So it's A.
