Why each option
Spoofing and SYN flood attacks are classified as Layer 2 DoS attacks, while password cracking and RF jamming fall into different attack categories entirely.
Spoofing attacks such as ARP spoofing and MAC address spoofing operate at Layer 2 (Data Link layer) by forging hardware or protocol addresses to disrupt or intercept network communications, making them a direct Layer 2 DoS vector.
SYN flood attacks are grouped with lower-layer DoS techniques in many security frameworks because they exploit fundamental connection-state exhaustion at the network stack level, overwhelming a target and denying service to legitimate users.
Password cracking is a credential-based attack aimed at gaining unauthorized access, not a network-layer denial-of-service technique.
RF jamming operates at Layer 1 (Physical layer) by disrupting radio frequency signals, not at Layer 2 of the OSI model.
