Which one of the following ether when heated with concentrated HI gives products through SN1 pathway

Mixed ethers containing tertiary alkyl group or allyl group or benzyl group undergo C-O bond fission when heated with conc.HI;The mechanism is SN1, the halogen atom goes with tertiary alkyl group or allyl group or benzyl group;CH3-O-CCH33→H+CH3-O+H-CCH33→slowCH3-OH+CH33C+; CH33C+ + I- →fast CH33C-I ;
