The correct option is A True
Colligative properties: Those physical properties of a solution which depend upon the number of particles in a given volume of the solution or the mole fraction of the solute are called colligative properties.
As Sugar exists as single-molecule in solution while NaCl gives two ions in solution so
The ratio of the value of any colligative property for NaCl solution of that of equimolal solution
of sugar is nearly 2:1
