Answer: A

Explanation:

The pass action is defined because it is sometimes easier to specify the class of data to ignore rather than the data you want to see. This can cut down the number of false positives and help keep down the size of log data. False positives occur because rules failed and indicated a threat that is really not one. They should be minimized whenever possible. The pass action causes the packet to be ignored, not passed on further. It is an active command, not a placeholder.
