For an aqueous solution, freezing point is \( -0.186{ }^{\circ} \mathrm{C} \). Elevation of the boiling point of the same solution is \( \left(\mathrm{k}_{\mathrm{f}}=1.86 \mathrm{k} \mathrm{kg} \mathrm{mol}^{-1}\right. \) and \( \left.\mathrm{K}_{\mathrm{b}}=0.52 \mathrm{k} \mathrm{kg} \mathrm{mol}^{-1}\right) \).
(A) \( 0.186^{\circ} \mathrm{C} \)
(B) \( 0.0512^{\circ} \mathrm{C} \)
(C) \( 1.86^{\circ} \mathrm{C} \)
(D) \( 5.12{ }^{\circ} \mathrm{C} \)
