Options:

A $\begin{matrix} A : H_{3} C - \underset{\underset{{SO}_{4}}{|}}{C} = {CH}_{2} & B : H_{3} C - \underset{\underset{O}{||}}{C} - {CH}_{3} \end{matrix}$
B $\begin{matrix} A : H_{3} C - \underset{\underset{OH}{|}}{C} = {CH}_{2} & B : H_{3} C - \underset{\underset{{SO}_{4}}{|}}{C} = {CH}_{2} \end{matrix}$
C $\begin{matrix} A : H_{3} C - \underset{\underset{O}{||}}{C} - {CH}_{3} & B : H_{3} C - C \equiv CH \end{matrix}$
D $\begin{matrix} A : H_{3} C - \underset{\underset{OH}{|}}{C} = {CH}_{2} & B : H_{3} C - \underset{\underset{O}{||}}{C} - {CH}_{3} \end{matrix}$
