# Refer the below figure: Compound on hydrolysis in aqueous acetone will give,

$(a)\;Mixture\; of\; (i)\; and\; (ii) \\ (b)\;Mixture \;of\; (i)\;and\; (ii) \\ (c)\;only \;(iii) \\ (d)\;only\;(i)$

It is $Sn_1$ reaction in which an intermediate carbacation is involved.
This carbocation is specially stabilized through in which $-O-CH_3$ group acts as a good electron donor.
Hence we will get a mixture of two products .
This is the mixture of (i) and (ii)
Hence a is the correct answer.
