$\Delta {\mathrm{T}}_{\mathrm{f}}={\mathrm{T}}_{\text{solvent }}-{\mathrm{T}}_{\text{solution }}={\mathrm{K}}_{\mathrm{f}}\times {\mathrm{m}}_{\text{observed }}$.

Greater the value of ${\mathrm{m}}_{observed}$, lower is the ${\mathrm{T}}_{solution}$.

In option (a), the correct order would have been (assuming 100% dissociation for each salt) $0.05MKN{O}_3>0.04MCaC{l}_2>0.14Mglucose>0.075MCuS{O}_4$.
