Which of the following command is used to enable logging in iptables?

 The command to enable logging in iptables for incoming packets is $ iptables -A INPUT -j LOG. This command appends a rule to the INPUT chain that logs the packet information. The -A flag is used to append the rule to the end of the specified chain, which in this case is INPUT, indicating that the rule applies to incoming packets. The -j LOG part of the command specifies the target of the rule, which is LOG, meaning that the packet will be logged.
