Answer: (C)

The minimum iOS version required for iCloud Keychain is iOS 7.0. This version introduced iCloud Keychain to securely store and manage passwords, credit card information, and other sensitive data across Apple devices. While other versions mentioned may have functionalities related to keychain services, iCloud Keychain specifically became available beginning with iOS 7.0.
