I totally agree with Robertlars "If the answer is C then where did it pull that IP address from found in the answer since that IP was not part of the question itself? " So I'm inclined towards D.

I think D is the right answer in this case. nslookup is the name of a program that lets an Internet server administrator or any computer user enter a host name (for example, "whatis.com") and find out the corresponding IP address or domain name system (DNS) record.

If the answer is C then where did it pull that IP address from found in the answer since that IP was not part of the question itself? I don't think the answer was C, and I think it is D, but I honestly am not certain.
