![**Question 14:** Which of the following is the major organic product in the reaction sequence below?
**Reaction sequence:**
\[ \text{H}_3\text{C--C}\equiv\text{C--H} \xrightarrow[\text{diethyl ether}]{\text{CH}_3\text{CH}_2\text{MgCl}} \xrightarrow[]{1) \ \text{cyclohexanone}} \xrightarrow[]{2) \ \text{H}_3\text{O}^+} \]
**Options:**
- **A)** Cyclopentanol with an ethyl group attached to the carbon adjacent to the hydroxyl group:
\[
\begin{array}{c}
\text{HO} \\
\vert \\
\text{CH}_2\text{CH}_3
\end{array}
\]
- **B)** Cyclohexanone with a methyl group substituent:
\[
\begin{array}{c}
\text{CHCH}_3
\end{array}
\]
- **C)** Cyclopentanol with a propynyl group attached to the carbon adjacent to the hydroxyl group:
\[
\begin{array}{c}
\text{HO} \\
\vert \\
\text{CH}_2\text{C}\equiv\text{CH}
\end{array}
\]
- **D)** Cyclopentanol with a propargyl group attached to the carbon adjacent to the hydroxyl group:
\[
\begin{array}{c}
\text{HO} \\
\vert \\
\text{CH}\equiv\text{C--CH}_3
\end{array}
