Adapter geniune or not ?

It is impossible to determine provenance from a photo alone. That said, nothing about the Power Adapter in your photo, or its markings, suggest that the Power Adapter is anything less than a genuine Apple Power Adapter.

That said, consider that a determined counterfeiter will likely have copied and visually duplicated the item exactly - including any markings thereon.

If purchased directly from Apple or an Apple Authorised Retailer, insofar as it is possible to be certain, you will have the genuine article. If purchased from an independent or online retailer, you don't have the same assurance of provenance.

This Apple Support document may be helpful to you - although the document is old and does not explicitly list your newer Apple 40/60W Dynamic Power Adapter:

No one can answer that question. Counterfeits can be quite well done.

Serial numbers can be copied, among other details.

If purchased directly from Apple or an authorized reseller, it is very likely genuine.

If purchased elsewhere, nobody here can tell if it is genuine, or if it is counterfeit.

Not trying to seem rude, but if you took the time to use the forum's search feature, you will find literally hundreds of posts asking fellow Apple Users to verify the authenticity of an Apple (like) device. If you did, you would see that you basically will get the same answer as you are seeing here.

FWIW, a video from Adam Savage (of Tested and MythBusters) that goes into details with legitimate and counterfeit AirPods Pro, and why some counterfeits can be easy to spot and some can be far more difficult:
