Compound $A\left({\mathrm{C}}_7{\mathrm{H}}_8\mathrm{O}\right)$ is insoluble in water, dilute HCJ and aqueous ${\mathrm{NaHCO}}_3\text{, }$ , it dissolves in dilute NaOH. When A is treated with ${\mathrm{Br}}_2$ water it is converted into a compound ${\mathrm{C}}_7{\mathrm{H}}_5{\mathrm{OBr}}_3$ rapidly. The structure ofA is:

From bromine water, Y must have the structure specified in option B in order to create ${\mathrm{C}}_7{\mathrm{H}}_5{\mathrm{OBr}}_3$. Since $-\mathrm{OH}\text{ and }-{\mathrm{CH}}_3$ are both members of the o,p directing group, they must both be in the meta position with regard to one another.
