Why each option

While `netstat` provides extensive information about network connections, interface statistics, and routing tables, it does not typically report on broadcast services directly.

Abroadcast servicesCorrect

`netstat` typically displays active network connections, routing tables, interface statistics, and masquerade connections (if the appropriate options are used), but it does not specifically list or report on 'broadcast services' as a distinct category in its output. Broadcast services are often configured at a higher application layer or observed via traffic analysis tools.

Binterface statistics

`netstat -i` shows network interface statistics, including MTU, RX/TX packets, errors, and collisions.

Cmasquerading connections

`netstat -M` (or `-m` on some systems) can show masquerade connection statistics or memory statistics for networking, depending on the system.

Dnetwork connections

`netstat -a` or `netstat -tulpn` shows all active network connections and listening ports.

Erouting tables

`netstat -r` shows the kernel IP routing table.
