What is the advantage of digital signatures over message authentication codes?

1. Digital Signature provides integrity verification while message authentication code can not 2. Digital Signature provides confidentiality while message authentication code can not 3. Digital Signatures provide authenticity while message authentication code cannot 4. Digital Signatures works faster then message authtication codes

Using the following chart as a reference, I'm leaning towards #2, but none of the choices really fit properly. …

Cryptographic primitive | Hash |    MAC    | Digital
Security Goal           |      |           | signature
------------------------+------+-----------+-------------
Integrity               |  Yes |    Yes    |   Yes
Authentication          |  No  |    Yes    |   Yes
Non-repudiation         |  No  |    No     |   Yes
------------------------+------+-----------+-------------
Kind of keys            | none | symmetric | asymmetric
                        |      |    keys   |    keys

Hopefully an expert here can clarify.
