Need Help Identifying is it a Acan , Favia, Or Micromussa ???

[1stPhantom]

A Friend of mine bought it and no longer wanted the frag so I got it off of him. Problem is he doesn’t know what it is he said he got it 2 days ago and forgot what it was. The receipt. Doesn’t state what it is either. I think I narrowed it down to these 3 but don’t know. Any input would be appreciated.

Appears to be a favia.
