Van't Hoff factors of aqueous solutions of `X,Y,Z` are `1.8,0.8 "and" 2.5`. Hence, their (assume equal concentrations in all three cases)

Options

A. `b.p.:XltYltZ`
B. `f.p.ZltXltY`
C. osmotic pressure `:X=Y=Z`
D. `v.p .: YltXltZ`

Explanation

To determine the order of boiling point, freezing point, osmotic pressure, and vapor pressure for the solutions of substances \(X\), \(Y\), and \(Z\) based on their Van't Hoff factors (\(i\)), we can follow these steps:

### Step 1: Understand the Van't Hoff Factor
The Van't Hoff factor (\(i\)) indicates the number of particles the solute breaks into when dissolved. The given values are:
- \(i_X = 1.8\)
- \(i_Y = 0.8\)
- \(i_Z = 2.5\)
