(A) Osmotic pressure, $\pi =$ iMRT (A) ${\pi }_{\text{Urea }}=1\times 0.2\mathrm{RT}=0.2\mathrm{RT}$ (B) ${\pi }_{\mathrm{NaCl}}=2\times 0.1\mathrm{RT}=0.2\mathrm{RT}$ (C) ${\pi }_{{\mathrm{BaCl}}_2}=3\times 0.05\mathrm{RT}=0.15\mathrm{RT}$ (D) ${\pi }_{{\text{ACC }}_3}=4\times 0.05\mathrm{RT}=0.2\mathrm{RT}$ $\therefore$ All solutions are isotonic with each other except $\mathrm{C}$.
