Which of the following compounds is most reactive toward acid-catalyzed hydration?

Which of the following shows the Lucas test instantaneously?

$CH_3-CH_2-CH_2-Br + NaOH \xrightarrow{C_2H_5OH} \text{Product } A$. Consider the above reactions,identify product $B$ and product $C$.

Alcohols $(i) \ CH_3CH_2CH_2OH$,$(ii) \ CH_3-CH(OH)-CH_3$ and $(iii) \ CH_3-C(CH_3)(OH)-CH_3$ were treated with Lucas reagent (Conc. $HCl + ZnCl_2$). What results do you expect at room temperature?
