- A.RSA
- B.ECC
- C.Diffie-Hellman
- D.AES
Why D is correct
AES (Advanced Encryption Standard) is the most widely used symmetric encryption algorithm. It supports key sizes of 128, 192, and 256 bits and is used to protect classified government data and commercial communications. RSA, Diffie-Hellman, and ECC are all asymmetric algorithms.
