D. Key

Are you 100% sure

Yes, I am 100% sure. The key is necessary to decrypt an encrypted message.

The correct answer is D. Key.

To decrypt an encrypted message, you need to provide the encrypted message itself and the key used to encrypt it to the decryption function. The key is a crucial piece of information that determines how the message is encrypted and helps to reverse the encryption process.
Without the correct key, it is usually extremely difficult, if not impossible, to decrypt the message properly. So, providing the correct key is essential for successful decryption.
