I agree with Britt, option C seems to be the most appropriate for parsing Class A addresses.

Haha, I bet the incident responder is going to have a field day with all those IP addresses in the logs. Time to get their grep on!

But option C uses the correct syntax to exclude Class A addresses.

Wait, is the regex in option B even valid? I'm not sure that's going to work as expected.

I think option A is the way to go. The regex looks correct, and it's redirecting the output to a file.

Option C looks good, it's using the right regex to filter out the internal Class A addresses from the log file.
