One correct answer

You replaced listen 127.0.0.1:80 with listen 80 and ran systemctl reload nginx without errors, yet ss -ltn still shows 127.0.0.1:80. Why?

• A The change was not saved to the file.
• B Port 80 is taken by another program.
• C ss shows sockets with a delay.
• D nginx could not open the new address next to the old one and stayed on the old one.
