What is the difference between the AES and RSA algorithms?
The correct answer is B. RSA is asymmetric, which is used to create a public/private key pair; AES is symmetric, which is. AES is a symmetric encryption algorithm using a single shared key, while RSA is an asymmetric algorithm that uses a mathematically linked public/private key pair.

Why each option
AES is a symmetric encryption algorithm using a single shared key, while RSA is an asymmetric algorithm that uses a mathematically linked public/private key pair.
AES is a symmetric algorithm, not asymmetric, so the premise that both are asymmetric is factually incorrect.
RSA is asymmetric, meaning it generates a public key for encryption and a private key for decryption, enabling secure key exchange and digital signatures without sharing a secret. AES is symmetric, using the same key for both encryption and decryption, making it significantly faster and suited for bulk data encryption. These two algorithms are often used together - RSA to securely exchange an AES session key.
RSA is an asymmetric algorithm, not symmetric, so the premise that both are symmetric is factually incorrect.
This reverses the two algorithms - AES is the symmetric algorithm and RSA is the asymmetric one, not the other way around.
