Freezing point of an aqueous solution is \( -0.186^{\circ} \mathrm{C} \). If the values of \( \mathrm{K}_{b} \) and \( \mathrm{K}_{f} \) of water are respectively \( 0.52 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1} \) and \( 1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1} \), then the elevation of boiling point of the solution in \( \mathrm{K} \) is
(a) \( 0.52 \)
(b) \( 1.04 \)
(c) \( 1.34 \)
(d) \( 0.052 \)
\( \mathrm{P} \)
