Answer: (B) Allow the firewall to accept inbound traffic to ports 80, 110, 143, and 443

Explanation:

Port 80 is used by HTTP, 110 by pop3 to retrieve emails from web servers, 143 by imap for internet messaging and 443 is used for TCP for websites using SSL. So if the firewall is allowed to accept inbound traffic to these ports 80,110,143 and 443 then it would be possible to retrieve emails.
