Answer

Correct option: C.
$\begin{matrix}
   \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,O  \\
   \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,||  \\
   {{(C{{H}_{3}})}_{2}}CHC{{H}_{2}}\,C\,H  \\
\end{matrix}$
c
$(A)$  $(CH_3)_2CH-CH_2-CO_2H$ 

$(B)$  $(CH_3)_2CH-CH_2-CH_2-OH$

$(C)$ $\begin{matrix}
   \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,O  \\
   \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,||  \\
   {{(C{{H}_{3}})}_{2}}CHC{{H}_{2}}\,C\,H  \\
\end{matrix}$
