I want to ask which one is correct, or both wrong , then what is the answer ?can you draw?
because i think H+ can both attach to C= C or C=O , i don't klnow how to choose

Where are you getting the OC₂H₅ group? There must be more to the question. Can you please post the whole thing?

sorry . the reactant is CH3OH

That would not give you OC₂H₅, that would give OCH₃.

Can you please post the WHOLE question, it wastes people's time on these forums to try and guess at an answer.

In any case, I would expect this reaction to simply react at the carbonyl. However, like most things in chemistry, there are nuances to this reaction, and I could see another 1,4 addition product. If you want to learn about the other product you could form, read about conjugate addition at wikipedia:

perhaps something analogous to THP addition?
