Give the reactivity in the decreasing order of the following alkynes towards nucleophilic addition reaction with ${\mathrm{MeO}}^{\mathrm{\Theta }}/\mathrm{MeOH}$.

(I) 

(II) $\mathrm{Me}-\equiv \mathrm{Me}$

(III) $\mathrm{Me}-\equiv -\mathrm{H}$

(IV) $\mathrm{H}-\equiv -\mathrm{H}$

• A

  (I) > (II) > (III) > (IV)

• B

  $\left(\mathrm{I}\right)>\left(\mathrm{IV}\right)>\left(\mathrm{III}\right)>\left(\mathrm{II}\right)$

• C

  $\left(\mathrm{IV}\right)>\left(\mathrm{III}\right)>\left(\mathrm{II}\right)>\left(\mathrm{I}\right)$

• D

  $\left(\mathrm{II}\right)>\left(\mathrm{III}\right)>\left(\mathrm{IV}\right)>\left(\mathrm{I}\right)$
