Identify the denial-of-service attack that is carried out using a method known as "bricking a system." Unlike other DoS attacks, it sabotages the system hardware, requiring the victim to replace or reinstall the hardware.
ICMP Flood Attack
Application Level Flood Attacks
Phlashing
Bandwidth Attacks

This type of DoS ( denial-of-service ) Attacks are called Phlashing.
It is permanent and irreversible damage to the system devices, hardware equipment and networks. So, it is rightly called " bricking the system " method.
The attacker sends fraudulent hardware updates to the devices causing the damage.
Earlier, phlashing is considered theoretical but now it is practically implemented by attackers and causing the damage.
The attacked devices are damaged permanently and cannot be reused, they must be replaced with new hardware.
So, option (c) is correct.
ICMP Flood Attack refers to flood of pings on the victim. So, option (a) is false.
Application Level flood attacks are the attacks at the application layer. These are two types (1) HTTP Flood and (2) Slowloris Attack. So, option (b) is false.
Bandwidth Attacks - As the name suggests the attacks are happening through the bandwidth ( traffic overload ) on the infrastructure.So, option (d) is false.
