Which type of chart display data in rings, where each ring represents a data series?

Doughnut chart

The correct answer is option 1- Doughnut chart.

Doughnut charts display data in rings, where each ring represents a data series. For example, the inner ring represents gas tax revenues, and the outer ring represents property tax revenues. 

It is similar to a pie chart but with a blank center. It is useful for showing proportional data across multiple categories and series. Single-series doughnut chart shows One ring whereas Multi-series doughnut chart (also known as a ring chart) shows Multiple concentric rings, each representing a different series.
