Answer: C

Explanation:

Encryption is the process of transforming data into an unintelligible form (ciphertext) to protect its confidentiality and integrity during transmission. It ensures that even if the data is intercepted, it cannot be understood or modified without the encryption key. Encryption helps in safeguarding sensitive information from unauthorized access and tampering.
