Correct option (c) CaCl₂

Explanation :

In solution, CaCl₂ gives three ions, KCI gives two ions while glucose and urea are covalent molecules so they do not undergo ionisation. Since osmotic pressure is a colligative property and it depends upon the number of solute particles (ions), therefore, 0.1 M solution of CaCl₂ exhibits the highest osmotic pressure.
