As we add dilute NaOH into the given compound, NaOH abstracts
proton from the alpha to carbonyl group and forms the different
enolates as shown in the given image. Then in dilute acidic
conditions, the formed enolates converted into keto group and that
time when keto enol tautomerization takes place, that time
stereocenters changes to form the more different products as shown
in the given image.
