Sorry – just gave a hasty answer. Correction:
B — Question specifies ARP not DNS – there’s a difference between ARP cache and DNS cache.
Not ( C ) because DNS poisoning goes after the DNS cache, not the ARP cache. But technically “modify the ARP cache” is actually “ARP Poisoning” not “spoofing”. Spoofing doesn’t modify the cache, but is BEST answer here.

C — DNS poisoning (also known as DNS spoofing) is a type of attack which uses security gaps in the Domain Name System (DNS) protocol to redirect internet traffic to malicious websites.
Not (B) because it only says “spoofing”, not DNS spoofing” , whereas (C) specifically says “DNS poisoning.”
