The correct answer is C. Encryption.

Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) are network security devices that monitor network traffic for suspicious activity and can block or alert on detected threats. Attackers may try to evade these systems by making the data incomprehensible without a specific key, certificate, or password, which is where encryption comes in.

Encryption is the process of encoding information so that only authorized parties can access it. It is commonly used to protect sensitive data, such as passwords, credit card numbers, and other personal information, from being intercepted or stolen. In the context of evading IDS/IPS devices, encryption can be used to make the data unreadable to anyone who doesn't have the proper decryption key.

Fragmentation is a technique where an attacker breaks up a packet into smaller pieces to avoid detection, but this does not make the data incomprehensible without a specific key, certificate, or password. Pivoting refers to an attack where an attacker gains access to one system and uses it as a jumping-off point to attack other systems, but this also does not make the data incomprehensible. Steganography is the practice of hiding secret information within other non-secret data, such as hiding a message within an image, but this does not involve encryption and the hidden message can still be detected by IDS/IPS devices.

Therefore, the correct answer is C. Encryption, as it allows the user to make the data incomprehensible without a specific key, certificate, or password, and is a commonly used technique for evading IDS/IPS devices.
