Explanation:
The correct answer is B because Network Load Balancer does not support TCP health checks, necessitating HTTP health checks. A basic web server on each instance can facilitate these checks. HTTPS health checks (Option C) are unnecessary for unsecured traffic. TCP health checks (Option D) are unsupported, and instances do not need to send traffic to the Network Load Balancer (Option A). Health checks ensure traffic is only directed to healthy instances, allowing for graceful shutdowns and connection closures.
