(C) Osmotic pressure is a colligative property,which depends on the number of solute particles in the solution. The formula is $\pi = iCRT$,where $i$ is the van't Hoff factor.For $M/10$ $HCl$,$i = 2$ $(H^+ + Cl^-)$.For $M/10$ urea,$i = 1$ (non-electrolyte).For $M/10$ $BaCl_2$,$i = 3$ $(Ba^{2+} + 2Cl^-)$.For $M/10$ glucose,$i = 1$ (non-electrolyte).Since $M/10$ $BaCl_2$ has the highest van't Hoff factor $(i = 3)$,it produces the maximum number of particles and thus has the highest osmotic pressure.
