Verified step by step guidance

Understand that osmotic pressure is a colligative property, which means it depends on the number of solute particles in a solution, not their identity.

Recall the formula for osmotic pressure: \( \Pi = iMRT \), where \( \Pi \) is the osmotic pressure, \( i \) is the van't Hoff factor (number of particles the solute dissociates into), \( M \) is the molarity of the solution, \( R \) is the ideal gas constant, and \( T \) is the temperature in Kelvin.

Identify that the concentration of solute particles (\( M \)) directly affects the osmotic pressure, as it is a part of the formula.

Note that while temperature (\( T \)) is a factor in the formula, the problem specifically asks for the factor responsible for osmotic pressure, which is primarily the concentration of solute particles.

Conclude that the correct answer is the concentration of solute particles, as it is the primary factor determining the osmotic pressure of a solution.
