What type of spoofing attack uses fake source IP addresses that are different than their real IP addresses?
The correct answer is B. IP spoofing. IP spoofing involves crafting packets with forged source IP addresses to disguise the attacker's true identity or impersonate another host.

Why each option
IP spoofing involves crafting packets with forged source IP addresses to disguise the attacker's true identity or impersonate another host.
MAC spoofing involves falsifying the Layer 2 hardware address on a network interface, not the Layer 3 IP address.
IP spoofing specifically refers to the manipulation of the source IP address field in a packet header, making traffic appear to originate from a different IP address than the actual sender. Attackers use this technique to bypass IP-based access controls, conduct anonymous attacks, or impersonate trusted hosts. It is a foundational technique used in amplification attacks, session hijacking, and evasion.
Application spoofing refers to impersonating a legitimate application or service, not forging network-layer source addresses.
Name spoofing is not a standard attack category; DNS spoofing poisons name resolution but does not describe forging source IP addresses directly.
