Answer: C

Explanation:

Symmetric encryption is a type of encryption where the same key is used for both the encryption and decryption processes. It is commonly employed to secure data at rest, such as on a hard drive or other storage media. With symmetric encryption, the key must be kept secret to ensure the confidentiality of the encrypted data.
