Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Option (A) is correct. Explanation is the correct reason for the statement.
The van't Hoff factor, symbol $i$ expresses how may ions and particles are formed (on an average) in a solution from one formula unit of solute.

When solute particles dissociate in solution, $i$ is greater than 1 and when solute particles associate in solution, $i$ is less than 1.
