The suggested answer is A, B, D.
Data labels in pie, donut, and single score visualizations can be shown as only percentages, as values, or as both, allowing for flexibility in presenting data. Legend percentages are shown along with values, which enhances the viewer's understanding by showing both the actual value and its percentage of the whole. It is also possible to set gradient, texture, or no color options for data display, enabling varied graphical representations to suit different presentation needs. The statement about the metric label name being displayed near the metric value is incorrect; usually, these visualizations focus on the data point itself rather than additional labels near the metric.
