Which of the following is converted into an alcohol on treatment with ${\mathrm{HNO}}_2$

Primary amines give alcohol when react with nitrous acid but methyl amine is an exception

${\mathrm{CH}}_3{\mathrm{NH}}_2+2{\mathrm{HNO}}_2\to {\mathrm{CH}}_3-\mathrm{O}-\mathrm{N}=\mathrm{O}+{\mathrm{N}}_2+2{\mathrm{H}}_2\mathrm{O}$

                                     or

$\begin{array}{r}2{\mathrm{CH}}_3{\mathrm{NH}}_2+2{\mathrm{HNO}}_2\to {\mathrm{CH}}_3{\mathrm{OCH}}_3+2{\mathrm{N}}_2+3{\mathrm{H}}_2\mathrm{O}\\ {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{NH}}_2+{\mathrm{HNO}}_2\to {\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}+{\mathrm{N}}_2+{\mathrm{H}}_2\mathrm{O}\end{array}$
