What is the purpose of the advantage rule in soccer?

The purpose of the advantage rule in soccer is to maintain the flow of the game by allowing play to continue when a foul has occurred, as long as the non-offending team can benefit from the situation. This rule recognizes that sometimes a team may be in a better position to capitalize on a play despite the foul, thereby promoting more dynamic gameplay and reducing stoppages. The referee assesses whether the non-offending team can maintain an advantage after the foul occurs; if they can, the game continues without interruption. This principle helps keep the game lively and exciting, as it prioritizes opportunity over strict adherence to stopping for every foul.

The other options would introduce limitations that conflict with the natural flow of the game. Stopping play immediately for any foul, suspending a player, or awarding a free kick would all serve to halt the ongoing action, which is contrary to the intention of encouraging continuous play when possible.
