The correct answer is B (HTTPS load balancer) because it is specifically designed to handle HTTPS traffic with SSL termination capabilities.

• HTTPS load balancer differs from an HTTP load balancer by using a target HTTPS proxy and requiring at least one SSL certificate installed on the target HTTPS proxy. It terminates the client SSL session at the load balancer and supports the QUIC transport layer protocol.

• Option A (TCP proxy) is incorrect as it does not support SSL offload and is not recommended for HTTP/S traffic.

• Option C (SSL proxy) is not recommended for HTTPS traffic. It is intended for non-HTTP(S) traffic, with HTTP(S) load balancing being the recommended choice for such traffic.

• Option D (HTTP load balancer) does not support SSL termination, making it unsuitable for this scenario.
