Symmetric encryption uses the same key for both encoding and decoding data, which is why it is often referred to as "shared secret" encryption. Asymmetric encryption, on the other hand, uses a public key to encrypt data and a private key to decrypt it, making it more secure but also slower than symmetric encryption. Option C is also incorrect - all encryption methods require a key to encrypt and decrypt data. Option D refers to public key encryption, which is a type of asymmetric encryption, not symmetric encryption.
