The key words in here are “impersonation” and “session token”
*B-DDOS is not a form of impersonation attack
*C- SMURF is not a form of impersonation attack The Smurf attack is a distributed denial-of-service attack in which large numbers of Internet Control Message Protocol (ICMP) packets with the intended victim’s spoofed source IP are broadcast to a computer network using an IP broadcast address.
*D- Ping of Death is not a form of impersonation attack
So it just leaves C as a possible answer, as it is a form of “impersonation” attack which is mitigated by the use of a “session token”
Explanation:
A replay attack (also known as playback attack) is a form of network attack in which a valid data transmission is maliciously or fraudulently repeated or delayed.
This is carried out either by the originator or by an adversary who intercepts the data and retransmits it, possibly as part of a masquerade attack by IP packet substitution (such as stream cipher attack).
