Best answer
Correct answer is (c) DNS cache

The explanation is: A DNS cache can be poisoned if it is having an erroneous entry where the invader gets to organize the DNS server & change different kinds of information on it. DNS poisoning is very dangerous because it can extend its reach from one DNS server to another.
