Which algorithm is an example of symmetric cryptography?

Explanation:
Symmetric cryptography uses the same secret key to both encrypt and decrypt data. AES is a symmetric block cipher that uses one key for both directions, making it efficient for protecting large amounts of data. The other options are not symmetric: RSA and ECC are asymmetric algorithms that rely on a key pair (public and private keys) for encryption and decryption, and SHA-256 is a cryptographic hash function used for integrity, not encryption. So AES best fits the idea of symmetric cryptography among these choices.
