The use of the same public key by both computers suggests the application of symmetric encryption. In this method, a single key is used for both encryption and decryption, contrasting with the dual-key approach of asymmetric encryption. Therefore, the answer is A: symmetric encryption. ;
Computer A and Computer B are using symmetric encryption since they are both utilizing the same key for encryption and decryption. This requires both computers to have the same access to the key for secure communication. Therefore, the answer is A: symmetric encryption.
