Selected Answer: B

To resolve the issue where incoming connections to ports 80 and 22 are being denied, you need to add rules to the INPUT chain of iptables to accept TCP traffic on these ports. This will allow the firewall to accept incoming HTTP and SSH connections, thus restoring access to the organization's web page and other services

This iptables command is adding a new rule to the INPUT chain in the iptables firewall. The rule allows incoming traffic on interface "eth0" using the TCP protocol, destined for port 80, to be accepted. The "-A" option is used to append the rule to the end of the chain, and the "-j" option specifies the target action for the rule, in this case ACCEPT. This command is typically used to configure a firewall to allow specific types of traffic to enter the system.
