A Correct answer
Explanation

The ping command sends ICMP Echo Request packets to a target host to test network connectivity and measure round-trip time. It's the standard tool for determining if a host is reachable on the network or Internet. The other options are incorrect: cmd is a Windows command prompt, nalookup appears to be a typo (likely nslookup for DNS queries), and ls-la lists files in Unix.
