The correct answer is B. In the security list, add an ingress rule for port 80 (http). Add stateful ingress rule to receive and respond to HTTP traffic.

Explanation
Add stateful ingress rule to receive and respond to HTTP traffic. Example: Instance A and Host B are communicating (Host B could be any host, whether an instance or not). The stateful ingress rule allows traffic from any source IP address (0.0.0.0/0) to destination port 80 only (TCP protocol). No egress rule is required to allow the response traffic.
