Mechanism of Dehydration, Methanol & Ethanol

Which of the following compounds produces methyl alcohol on treatment with hot concentrated HI?

Explanation:

Hint: $SN_1$ reaction mechanism depends on stability of carbocation.

Explanation:
${CH}_{3} - {C_{|}^{|}}_{{CH}_{3}}^{{CH}_{3}} - O - {CH}_{3} + HI \to {CH}_{3} - {C_{|}^{|}}_{{CH}_{3}}^{{CH}_{3}} - I$ ${CH}_{3} - C_{|}^{|} {CH}_{3} {CH}_{3} - O - {CH}_{3} + HI \to {CH}_{3} - C_{|}^{|} {CH}_{3} {CH}_{3} - I$ $+$ $+$ $HO - {CH}_{3}$ $HO - {CH}_{3}$
