Correct Answer: C

Solution:

$ \underset{\begin{smallmatrix} \text{Acetoacetic ester} \\ \text{ ( keto form)} \end{smallmatrix}}{\mathop{CH_3-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-CH_2-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-O-C_2H_5}} $ ⇌ $ \underset{\text{(enolic form)}}{\mathop{CH_3-\overset{OH}{\mathop{\overset{|}{\mathop{C}}=}}CH-\overset{O}{\mathop{\overset{||}{\mathop{C}}}}-O-C_2H_5}} $
