Which hub(s) is/are active during the transition shift?

The correct choice indicates that both hubs are active during the transition shift. This is important because during the transition shift, gameplay dynamics can change significantly, and the ability to utilize both hubs allows teams to optimize their scoring strategies. By having both hubs active, teams can potentially adjust their tactics based on the opposing team's performance and their own scoring needs.

The inclusion of both hubs in the gameplay during this phase enhances the strategic element of the match, providing teams with more options to respond to the evolving conditions on the field. This flexibility is crucial for maintaining competitiveness and scoring effectively.

The other choices do not capture the full context of gameplay during the transition shift, where relying solely on one hub or none would limit strategic opportunities, ultimately reducing a team's effectiveness in scoring. Therefore, recognizing that both hubs are active is critical for a complete understanding of the rules governing the transition phase in FRC competitions.
