A junior analyst is trying to use the tcpdump -i eth1 command on an Ubuntu system, but it is not working. What could be the problem?
A. The tcpdump command requires root level privilege.
B. The tcpdump command requires the Ethernet adapter to be in non-promiscuous mode.
C. The tcpdump command -i option used to specify the interface is an invalid option.
D. The tcpdump command used is missing some of the required options (such as -n and -v).
