Doughnut charts:

(A) Contains More than one data series
(B) Comparable with Pie Chart
(C) Comparable with bar graph
(D) Comparable with Line Chart

Choose the correct answer from the options given below:

(A) and (B) only

The correct answer is Option (3) → (A) and (B) only.

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. 

(A) Contains More than one data series- It is true. Doughnut charts can display multiple data series (unlike pie charts which display only one). Each additional series is represented as another ring in the chart.

(B) Comparable with Pie Chart - It is true. Data can be arranged in columns or rows only on a worksheet and can be plotted in a doughnut chart. Like a pie chart, a doughnut chart shows the relationship of parts to a whole, but it can contain more than one.

(C) Comparable with bar graph - It is not true. Bar charts are used to depict the comparison of absolute values of data (e.g. sales, production, etc.) at discrete points (e.g. time intervals, products, etc.). Doughnut charts show percentage or proportion, not actual values in bar format. So they are not directly comparable.

(D) Comparable with Line Chart- It is not true. Line charts are used for trends over time (continuous data), while doughnut charts show part-to-whole relationships. So they serve very different purposes.
