Which among the following reactions does not give methyl alcohol?

The correct option is C The reaction of ethylene with $H_2{SO}_4$ at ${80}^{o}C$
The reaction of ethylene with $H_2{SO}_4$ at ${80}^{o}C$ gives ethyl hydrogensulphate.
$C{H}_2=C{H}_2+H_{2}S{O}_4\to C{H}_{3}C{H}_{2}OS{O}_{2}OH$
Water gas (carbon monoxide and hydrogen) at high temperature gives methanol.
$CO+2H_2\to C{H}_{3}OH$.
Alkaline hydrolysis of methyl bromide gives methanol
$C{H}_{3}Br+H_{2}O\to C{H}_{3}OH+HBr$
