Answer options:

The same key is used for both encryption and decryption.

A public key encrypts and a private key decrypts.

It is generally slower than asymmetric encryption.

It solves the key exchange problem inherently.

How to approach this question

A.The same key is used for both encryption and decryption.✓ Correct

Symmetric encryption uses a single shared secret key for both encryption and decryption (e.g., AES). Asymmetric encryption uses a pair of keys (Public/Private).

Common mistakes
