Final answer:
The number of fouls that must occur for a shootout varies by sport, but if this question relates to futsal, after five fouls a shootout may occur.
Step-by-step explanation:
In team sports, the rule regarding shootouts after a certain number of fouls differs based on the specific game. However, the phrasing of this question suggests it may be referencing soccer (football), where after five fouls, a series of penalty kicks or a shootout might take place, such as in futsal. In standard soccer matches, penalty kicks are given for fouls that occur inside the penalty area, regardless of the number of total fouls. If this question pertains to futsal rules, the correct answer is B) Five. If it refers to another sport, additional context would be required to provide the correct number.
