• A. $\text{(a) -(iii), (b) -(iv),(c) -(i), (d)-(ii)}$
• B. $\text{(a) -(iv), (b) -(i),(c) -(iii), (d)-(ii)}$
• C. $\text{(a) -(iv), (b) -(iii),(c) -(ii), (d)-(i)}$
• D. $\text{(a) -(iv), (b) -(iii),(c) -(i), (d)-(ii)}$

Answer 1

The correct option is D $\text{(a) -(iv), (b) -(iii),(c) -(i), (d)-(ii)}$

$\text{Cheese - Liquid dispersed in solid}\text{Pumice stone - Gas dispersed in solid}\text{Hair cream - Liquid dispersed in liquid}\text{Cloud - Liquid dispersed in gas}$

$\therefore$ correct answer is

$\text{(a) -(iv), (b) -(iii),(c) -(i), (d)-(ii)}$
