The correct answer is C. netstat. The netstat command displays active TCP connections, listening ports, and network statistics, making it the correct tool to view established FTP connections to a server. No other listed command provides connection state information.

Why each option
The netstat command displays active TCP connections, listening ports, and network statistics, making it the correct tool to view established FTP connections to a server. No other listed command provides connection state information.
The ifconfig (or ipconfig on Windows) command displays network interface configuration such as IP address and subnet mask, not active network connections.
The nslookup command queries DNS servers to resolve hostnames to IP addresses and provides no information about active TCP/IP connections.
The netstat utility shows all active network connections along with their state (e.g., ESTABLISHED), local and remote addresses, and port numbers. Running 'netstat -an' or 'netstat -p tcp' will reveal any established connections to the server's FTP port (21), confirming whether a client is actively transferring files.
The arp command displays and manages the ARP cache, which maps IP addresses to MAC addresses, and does not show TCP connection states or port usage.
