Answer: Employing AWS AppConfig for feature flag management to govern feature visibility.
The correct answer is C. AWS AppConfig is a service designed specifically for the management of configuration data which can include feature flags. It allows developers to seamlessly activate and deactivate feature flags, ensuring that features remain hidden from users until they are ready for public release. The other options, like AWS AppSync, Amazon DynamoDB, and AWS Amplify DataStore, are not primarily intended for feature flag management, making AWS AppConfig the most suitable solution for this requirement.
