Hint: We have to remember that the Van’t Hoff derives an equation based on the change in the equilibrium constant and change in temperature in a chemical reaction given the standard enthalpy change. With the help of Van’t Hoff equation, in the thermodynamic system we can explain the changes that occur in state function.

Think about a weakened arrangement of a volume V (in dm3) containing W grams of a substance having atomic weight M at an outright temperature T. At that point, centralization of the arrangement, $C = n/V$ and No. of moles of the substance, $n = W/M$.
By van't Haff: Boyle's law, at a consistent temperature, the osmotic weight of an answer is legitimately relative to its molar fixation or conversely corresponding to the volume of the arrangement. Subsequently,
$\pi \propto C$ (When temperature is steady)
Van't Hoff Charle's law at the consistent focus the osmotic weight of a weaken arrangement is straightforwardly relative to the outright temperature (T) for example
$\pi \propto T$
$\pi \propto CT$
$\pi = CRT$
$\pi = \dfrac{n}{V}RT$
Where, $\pi$ is pressure, T is temperature, R is a gas constant, and n is the number of moles and V is volume.
The condition is called van't Hoff general arrangement condition.
R is steady of proportionality, likewise called general arrangement consistent or gas consistent.
Therefore, the option (A) is correct.

Note:
-We all know depression in melting point is directly associated with van't Hoff factor $\left( i \right)$ consistent with which greater the worth of van't Hoff factor greater are going to be Depression in melting point.
-We can calculate the melting point depression using the formula,
$\Delta Tf = i \times Kf \times molality$
Where , the melting point depression is denoted as $\Delta Tf$ , $Kf$ is that the melting point depression constant, and that $i$ is that the van ‘t Hoff factor.
-The van't Hoff factor $\left( i \right)$ is the total number of ions after dissociation or association or the total number of ions before dissociation or association.
