Which of the following will have the highest depression in freezing point when their concentration is $0.1 \ M$?

Determine the expected value of $\Delta T_{f}$ for $1 \ m$ $CaCl_{2}$ solution if $1 \ m$ urea solution has $\Delta T_{f}$ value '$x$' $K$.

The freezing point of a $0.05 \ m \ BaCl_2$ solution in water ($100 \%$ ionisation) is about $(K_f = 1.86 \ K \ kg \ mol^{-1})$. (in $^oC$)

What is the percentage of dissociation of a $0.011 \ m$ aqueous solution of $K_3[Fe(CN)_6]$ having a freezing point of $-0.063 \ ^oC$? (Given: $K_f = 1.86 \ K \ kg \ mol^{-1}$ for water)

The freezing point of an aqueous solution which contains $5\%$ by mass urea,$1.0\%$ by mass $KCl$,and $10\%$ by mass glucose is ........ $K$. $\left( K_f(H_2O) = 1.86 \ K \ kg \ mol^{-1} \right)$

Maximum depression in freezing point is caused by
