To test whether your firewall rules are working properly, you can enable Firewall Rules Logging on the latest rules that were changed and use Logs Explorer to analyze whether the rules are working correctly. Firewall Rules Logging lets you audit, verify, and analyze the effects of your firewall rules. It generates an entry called a connection record each time a firewall rule allows or denies traffic. You can view these records in Cloud Logging and export logs to any destination that Cloud Logging export supports. By enabling Firewall Rules Logging on the latest rules that were changed, you can determine if a firewall rule designed to deny traffic is functioning as intended. This will help you identify whether the recent change to your firewall rules is responsible for the reported outage. Therefore, option A is the correct answer.
