Among the following, the products formed by the reaction of anisole with $$\mathrm{HI}$$ are

Which is most VISCOUS?

A compound $$'A' \left(\mathrm{C}_7 \mathrm{H}_8 \mathrm{O}\right)$$ is insoluble in $$\mathrm{NaHCO}_3$$ solution but dissolve in $$\mathrm{NaOH}$$ and give a characteristic colour with neutral $$\mathrm{FeCl}_3$$ solution. When treated with bromine water compound '$$A$$' forms the compound $$B$$ with the formula $$\mathrm{C}_7 \mathrm{H}_5 \mathrm{OBr}_3$$. '$$A$$' is
