The correct answer is:

\overset{O}{\overset{| |}{C}} - O H

\overset{O}{\overset{| |}{C}} - N H_{2} \overset{P_{2} O_{5}}{\to}

C \equiv N

\overset{(i) C H_{3} M g B r (i i) H_{3} O^{+}}{\to}

\overset{O}{\overset{| |}{C}} - {C H}_{3}

\overset{(i) I_{2} + Ca {(OH)}_{2} (ii) H_{2} O}{\to}

\overset{O}{\overset{| |}{C}} - O H
