Explanation

ARP (Address Resolution Protocol) spoofing involves an attacker sending forged or gratuitous ARP reply packets on a local network segment to associate their MAC address with a legitimate IP address (such as a gateway). In a packet capture, this manifests as multiple ARP replies claiming the same IP address is mapped to different MAC addresses-or a host repeatedly broadcasting unsolicited ARP replies. This poisons the ARP caches of other hosts, enabling man-in-the-middle interception of traffic. The other options involve different traffic patterns: a broadcast storm shows exponentially growing broadcast frames, a Smurf attack uses ICMP echo requests to broadcast addresses, network enumeration shows systematic probing of ports/addresses, and a zero-day exploit would involve specific vulnerability exploitation traffic.
