Answer: Allow incoming traffic on port 443 from the Internet for the web server subnet.
The correct answer is A. Users access the web front end of App1 using HTTPS, which operates over port 443. Therefore, an incoming security rule for port 443 is needed. This rule should be associated with the subnet containing the web servers to ensure secure access. Outgoing rules are irrelevant in this scenario since the goal is to allow users to access the web front end, not to control outbound traffic.
