Although mostly keto form is more stable but in some cases enol form is more stable than keto. It depends on number of factors such as: 1. Aromaticity- if after formation of enol aromaticity is developed in the molecule then enol will be stable. 2. Hydrogen bond- if any hydrogen bond is formed then enol form is more stable. Apart from these any factor which will stabilize the double bond formed will also shift the reaction towards enol side.
correct option is E, as an aromatic system is formed after enolization. Explaination is provided below:
As we can see above the alpha H next to carbonyl is needed for enolization. (a,b,c are possible steps)
