Solution

The correct option is C $P_{1} < P_{2} < P_{3} < P_{4}$
At a particular temperature pV = constant.

$P_{1} V_{1} = P_{2} V_{2} = P_{3} V_{3} = P_{4} V_{4}$

As $V_{1} > V_{2} > V_{3} > V_{4}$ , therefore we can say $P_{1} < P_{2} < P_{3} < P_{4}$ .

Hence, the correct answer is option $C$ .
