The freezing point depression constant \(\left(K_{f}\right)\) of benzene is \(5.12 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\). The freezing point depression for the solution of molality \(0.078 \mathrm{~m}\) containing a non-electrolyte solute in benzene is (rounded off upto two decimal places):
A \(0.20 \mathrm{~K}\)
B \(0.80 \mathrm{~K}\)
(c) \(0.40 \mathrm{~K}\)
D \(0.60 \mathrm{~K}\)
