We know that nucleophilic substitution always compets with elimination. Tertiary alkyl halide preferably undergoes elimination under the reaction conditions to from alkene. Therfore, the correct method to prepare the ether is
(ii) `CH_(3)BrNaOC(CH_(3))_(3)rarrunderset("Methyl tert-butyl ether")(CH_(3)-O-(CH_(3))_(3))+NaBr`
