Consider following solutions :
I: `1M` aqueous glucose solution II: `1M` aqueous sodium chloride solution
III: `1M` aqueous ammonium phosphate solution IV: `1M` benzoic acid in benzene
Select correct statements for the above solutions :

Options

A. All are isotonic solutions
B. III is hypertonic of I,II and IV
C. IV is hypotonic of I,II and III
D. II is hypotonic of III but hypertonic of I and IV

Explanation

To solve the problem, we need to analyze the four given solutions based on their osmotic pressure, which is influenced by the van't Hoff factor (i). The osmotic pressure (π) can be expressed as:

\[ \pi = iCRT \]

Where:
- \(i\) = van't Hoff factor (number of particles the solute dissociates into)
