What elements may affect the league and division structure during matches?

The correct response highlights that alliances selection and the potential replay of matches due to arena faults can directly impact the league and division structure during competitions. In various robotics competitions, alliances are formed strategically based on team strengths and strategies, which can lead to different results, affecting overall standings and rankings within the league.

Furthermore, if a match needs to be replayed due to issues such as arena faults—like malfunctioning equipment or environmental hazards—this can also influence the outcomes for teams, thus altering league standings. These factors contribute to the dynamic nature of competition and how teams rank in relation to one another throughout the season.

In contrast, focusing solely on team actions or the decisions made by referees does not encompass the broader structural implications. External audience feedback, while potentially influential in other contexts, does not directly alter the league and division structures in a competitive setting like the FTC.
