Correct Answer - B
`CH_(3)COOC_(2)H_(5)+CH_(5)-overset(O)overset(||)(C)-OC_(2)H_(5)overset(C_(2)H_(5)ONa)to`
`CH_(3)-overset(O)overset(||)(C)-CH_(2)-COOC_(2)H_(5)overset(H^(+))to`
`CH_(3)-COCH_(2)COOHoverset("Heat")toCH_(3)-overset(O)overset(||)(C)-CH_(3)+CO_(2)`
`beta`-Keto acids, on heating undergo decarboxylation
