Chain noise loud, Is it time for the replacement of this sprocket set?

How can it be hooked in the wrong direction, it's the front sprocket that pulls the chain, rather than the chain pulling the sprocket?

It looks to me like the hook tips are pointing forward, the normal wear pattern for a front sprocket.

Really?
Well I've learned something new today, although I've not really put too much thought into it before to be honest. I just see hooks and presume it's fooked.  :lol
