Ring will be opened as Etona will take h+ as it is good base and stable Carbocation will be formed and will get attacked by the carnation that will form

@!Nimay¡ help me out!
Comrade Rock Astley
You might have this EtO- abstracts a hydrogen from the carbon that’s meta to the ketone
Comrade Rock Astley
Then this might happen

What's the answer then I didn't get it actually Perhaps...given answer is D
Comrade Rock Astley
Sorry I was out at that time Yeah at that time I was wondering about B and D You’d have a similar mechanism for D The difference is that the anion is in resonance with the carbonyl group @iTeachChem Sir what’s your opinion on this?

Make carbanion at the left (so it stays in conjugation with the carbonyl group)
Comrade Rock Astley
yeah (correction)
Comrade Rock Astley
Got it B would form as the kinetic product or a minor product D is definitely more stable So yeah it's D

But after that we let it through hydrolysis ig...in order to get the answer right. But water is not mentioned in the question. ...?
Comrade Rock Astley
It’s understood that the solvent is water
