ROFL hahahaha
39Spontaneous transformation means that there's obviously a stabilizing (read : six membered) transition state and some quick tautomerization involved. I'd put my money on b) being the answer in that case.
1After the tautomerisation has taken place according to Pritish Bhaiyya ' s mechanism , obviously there will be a development of " negative charge " on the " α " carbon and a development of " positive charge " on the " β " carbon . Since " - N H 2 " is an electron releasing group , hence it ' ll try to stick to the " β " carbon only , because if it doesn't , then the density of " negative charge " on the " electropositive carbon atom " would increase . Hence , I think " ( b ) " is the correct option .
