Correct Answer: C
Solution :
\[\underset{\text{Bleaching powder}}{\mathop{CaOC{{l}_{2}}}}\,+{{H}_{2}}O\to Ca{{(OH)}_{2}}+C{{l}_{2}}\] \[C{{l}_{2}}+{{H}_{2}}O\to 2HCl+O\] \[\underset{\text{ethanol}}{\mathop{{{C}_{2}}{{H}_{5}}OH}}\,+O\to \underset{\text{Acetaldehyde}}{\mathop{C{{H}_{3}}CHO}}\,\ +{{H}_{2}}O\] \[C{{H}_{3}}CHO+3C{{l}_{2}}\to \underset{\text{chloral}}{\mathop{CC{{l}_{3}}CHO}}\,+3HCl\] \[2CC{{l}_{3}}CHO+Ca{{(OH)}_{2}}\to \underset{\begin{smallmatrix} \text{chloroform or } \\ \text{trichloromethane} \end{smallmatrix}}{\mathop{2CHC{{l}_{3}}}}\,+{{(HCOO)}_{2}}Ca\]
