Correct answer
C(A) - (II), (B) - (III), (C) - (I), (D) - (IV)
Step-by-step explanation
Negative charged sol = CdS sol (II)
Macromolecular colloid = starch (III)
Positively charged sol = Fe2O3.xH2O (I)
Cheese = gel (IV)
Macromolecular colloid = starch (III)
Positively charged sol = Fe2O3.xH2O (I)
Cheese = gel (IV)
