Why each option

This question describes the technique of network sniffing, which passively captures and analyzes network traffic to extract information.

ANetwork SniffingCorrect

Network sniffing is a passive technique where a network interface controller (NIC) captures all packets traversing a network segment, regardless of their intended destination. It involves decoding protocols and examining headers and payloads to extract relevant information, serving both as a review technique for troubleshooting and a reconnaissance technique for security analysis.

BPacket Sniffing

Packet sniffing is synonymous with network sniffing, but "network sniffing" is often preferred as the umbrella term for the activity described.

CNetwork Monitor

Network Monitor is a generic term for a tool or program that monitors network activity, but not the specific passive technique of capturing and analyzing packets.

DHacking Sniffing

"Hacking Sniffing" is not a standard or recognized technical term for this activity.
