Your organization is planning to host a global event and expects a significant spike in web traffic. Which GCP service can automatically adjust the number of VM instances based on HTTP load, including SSL offloading?

*Explanation:* To handle a significant spike in web traffic with automatic scaling and SSL offloading, the best choice is **Cloud Load Balancer with HTTPS load balancing**. It automatically adjusts the number of VM instances based on HTTP load and provides SSL offloading. App Engine is for application hosting but doesn't directly handle SSL offloading, Cloud Functions are event-driven and not suited for this requirement, Cloud CDN is primarily for content delivery, and Cloud Armor is focused on security, not load balancing or SSL offloading.
