Correct answer: C
The correct option is C. AES (Advanced Encryption Standard) is a symmetric key symmetric cipher that uses the same secret key for both encryption and decryption. In contrast, El Gamal, Rabin, and RSA are all asymmetric (public key) cryptosystems that utilize a mathematically related public-private key pair.
