Which option is likely available for gamification features within the event app?

The option related to gamification features within the event app is a leaderboard. Leaderboards are a common gamification tool, as they foster competition among participants by displaying their scores or achievements relative to others. This feature encourages engagement and interaction, as attendees can see how they rank in various activities, such as participating in sessions, completing quizzes, or engaging with sponsors.

In contrast, interactive maps, surveys, and video streaming do not inherently have gamification elements. While these features enhance the user experience, they do not provide a competitive or game-like aspect that stimulates participation in the same way that leaderboards do. Therefore, leaderboards stand out as the primary option associated with gamification features within the event app.
