Gateway Load Balancer is a SKU of the Azure Load Balancer portfolio catered for high performance and high availability scenarios with third-party Network Virtual Appliances (NVAs). With the capabilities of Gateway Load Balancer, you can easily deploy, scale, and manage NVAs. Chaining a Gateway Load Balancer to your public endpoint only requires one selection.

C. Azure Application Gateway Azure Application Gateway is designed for web application load balancing and can distribute traffic to backend servers based on various routing rules, including round-robin, least-connections, and more. In your case, it would be suitable for load balancing incoming traffic across NVA1 and NVA2 in VMSS1. It's also designed to minimize administrative effort when load balancing web traffic to your backend resources.

Gateway Load Balancer seems the best option. "One of the main advantages of this NVA injection method is that Source Network Address Translation (SNAT) isn't required to guarantee traffic symmetry. Another benefit of this design option is that the same NVAs can be used to inspect traffic to/from different VNets, thus achieving multitenancy from the NVA perspective. No VNet peering is required between the NVA VNet and the workload VNet(s), and no User-Defined Routes are required in the workload VNet, which dramatically simplifies the configuration." https://learn.microsoft.com/en-us/azure/architecture/reference-architectures/dmz/nva-ha
