A. B. C. D.

D.

The best encryption solution to deploy in this situation is D. AES-256.

AES-256 (Advanced Encryption Standard-256) is a symmetric encryption algorithm that uses a 256-bit key. It is widely used for encryption and decryption of sensitive data because of its high security and efficiency. AES-256 is considered one of the most secure encryption algorithms, as it would take an impractical amount of time to brute-force attack the encryption.

Elliptic curve encryption is a type of public-key encryption that uses the mathematics of elliptic curves to generate keys. It is useful for encrypting data in situations where a secure channel for key exchange is not available. However, it is not as widely used as symmetric encryption algorithms like AES-256 for encrypting large amounts of data.

One-time pad encryption is a type of symmetric encryption that uses a randomly generated key that is only used once. While it is theoretically unbreakable, it is not practical for encrypting large amounts of data due to the need for a pre-shared secret key that is as long as the data being encrypted.

3DES (Triple Data Encryption Standard) is a symmetric encryption algorithm that uses three separate 56-bit keys to provide a total key length of 168 bits. While it was widely used in the past, it has been largely replaced by AES-256 due to its slower processing speed and lower security.

In summary, AES-256 is the best encryption solution to deploy in this situation due to its high security and efficiency.
