Answer: Associates
When solute particles associate in solution, $i$ is less than 1, when solute particles dissociate in solution,$i$ is greater than 1, and $i$ equals 1 if they neither associate nor disassociate.
$\Rightarrow$ If $i \lt 1 \rightarrow$ two or more solute molecules associate to form a bigger molecule. The number of effective molecules in the solution, therefore decreases.
