What data update settings can you enable for a single score visualization to update the score in real-time?

The selection of real-time update as the correct answer is based on its functionality, specifically designed for score visualizations that need to reflect the latest data continuously. This feature enables the score visualization to fetch and display the most current information instantly, without the need for manual refreshes or preset time intervals.

In scenarios where timely data presentation is crucial, such as dashboards that monitor metrics that fluctuate frequently, the real-time update setting ensures that users are always viewing the latest available data, enhancing decision-making efficiency and accuracy.

The other choices relate to updating mechanisms but do not provide the continuous update capability that real-time updates offer. For example, background refresh intervals define how often data is refreshed but do so based on a predetermined schedule rather than instantly. Similarly, showing score update time and live refresh date serve to inform users about when the last update occurred rather than actively updating the score in real-time. Therefore, real-time update is the most suitable choice for ensuring score visualizations are current, reflecting any instantaneous changes in the underlying data.
