Answer:
Correct Answer: D
Solution:
$ CH-COOK \\ ||| \\ CH-COOK \\ +2H_2O\xrightarrow{Electrolysis} $
$ \underset{{}}{\mathop{\underbrace{ CH \\ ||| \\ CH \\ } _{Cathode}}}+2CO_2+\underbrace{2KOH+H_2} _{Anode} $
$ CaC_2+2H_2O\to Ca{{( OH )}_2}+CH\equiv CH $
$ \underset{Br}{\mathop{\underset{|}{\mathop{CH_2}}}}-\underset{\underset{Br}{\mathop{|}}}{\mathop{CH_2}}+2KOH\to CH_2=CH_2+2KBr+2H_2O $
