Which algorithm provides encryption and authentication for data plane communication?

The correct answer is A. AES-GCM. AES-GCM can do encryption like all other AES and has an authentication tag, rest of the options can be used for encryption or authentication, but not both.

Explanation

AES-GCM can do encryption like all other AES and has an authentication tag, rest of the options can be used for encryption or authentication, but not both. In cryptography, Galois/Counter Mode (GCM) is a mode of operation for symmetric-key cryptographic block ciphers which is widely adopted for its performance. GCM throughput rates for state-of-the-art, high-speed communication channels can be achieved with inexpensive hardware resources. The operation is an authenticated encryption algorithm designed to provide both data authenticity (integrity) and confidentiality.
