Consider the following reaction: \[C{{H}_{3}}C{{H}_{2}}\xrightarrow{B{{r}_{2}}/hv}(A)\xrightarrow{alc.\,KOH}(B)\]  \[\xrightarrow{NBS}(C)\xrightarrow{+{{(C{{H}_{3}})}_{2}}CHONa}(D)\] in this sequence will be

A)  \[{{(C{{H}_{3}})}_{2}}CH-C{{H}_{2}}-CH=C{{H}_{2}}\]

B)  \[{{(C{{H}_{3}})}_{2}}CHOH\]

C)  \[{{(C{{H}_{3}})}_{2}}CH-O-C{{H}_{2}}-CH=C{{H}_{2}}\]

D)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\mathop{C}}\,H-CH=C{{H}_{2}}\]
