The correct answer is C. SSL proxy, as it supports TCP traffic with the added ability to offload SSL. According to Google Cloud's documentation on Choosing a Load Balancer, the SSL Proxy Load Balancing terminates user SSL (TLS) connections at the load balancing layer and then balances the connections across your instances using either SSL or TCP protocols. It's specifically designed for non-HTTP(S) traffic, making it the ideal choice for this scenario. Options A. HTTP load balancer and D. HTTPS load balancer are incorrect because they are only recommended for HTTP or HTTPS traffic. Option B. TCP proxy is also incorrect as it does not support SSL offload.
