Answer:
Option A
Explanation:
The equation that represents van't Hoff general equation $\pi =\frac{n}{V}RT$
This equation was obtained by combining three laws.
(i) Boyle-van't Hoff law $\Rightarrow$ $\pi \propto C$
If V litres of solution contains n moles of solute,
then C=$\frac{n}{V}$
Then, $\pi V$ = constant
(ii) Charles'-van't Hoff law $\Rightarrow$ $\pi \propto T$
$\frac{\pi}{T}$= Constant
(iii) Avogadro- van't Hoff law $\Rightarrow$ $\pi \propto n$
where, n= number of moles of solute per litre of solution
