Answer: Authorize the central AWS account's EventBridge to access other accounts, integrating EventBridge event buses from receiver accounts as additional targets in the existing rule.
The correct answer is C. This approach leverages the capabilities of Amazon EventBridge for cross-account event sharing. By granting permission to the central AWS account for EventBridge to access the receiver AWS accounts, and then adding an EventBridge event bus in each receiver account as a target to the existing EventBridge rule, you can ensure that events are propagated across multiple AWS accounts. This method does not require any changes to the existing SCM system configuration. Option A, B, and D do not address the need for a cross-account event propagation without altering the SCM configuration.
