An aqueous solution boils at \( 101^{\circ} \mathrm{C} \). What is the freezing point of the same solution? (Given : \( K_{f}=1.86^{\circ} \mathrm{C} / \mathrm{m} \) and \( K_{b}=0.51^{\circ} \mathrm{C} / \mathrm{m} \) )
(a) \( 3.647^{\circ} \mathrm{C} \)
(b) \( -3.647^{\circ} \mathrm{C} \)
(c) \( -0.364^{\circ} \mathrm{C} \)
(d) None of these
