C is the CLIENT cache- Things that the server OS had to look up for itself as a client (like if you used IE to go to MS.com).
A
is the SERVER cache- things the DNS server program had to look up for clients.

actually that’s not true. ipconfig.exe /displaydns works fine, but it doesn’t return the ttl from the dns server cache but from the dns client. So answer is A.
