Step 1: Understanding the Concept:
Excel offers many chart types, and each shows data in its own shape.
The question asks for the chart in which data appears in rings and each ring is one data series.
Step 2: Working Out the Answer:
A doughnut chart looks like a pie chart with a hole in the middle.
It is made of concentric rings. Each ring is one data series, and its slices show the share of each category.
This matches the description in the question exactly.
So the answer is Doughnut chart, option (A).
Step 3: Why the Other Options Are Wrong:
Option (B): A radar chart draws values on axes that spread out from a centre point. The points are joined into a web-like shape, not rings.
Option (C): A pie chart shows only one data series in a single circle. It has no rings for several series.
Option (D): Option (D) says both (B) and (C). Since neither (B) nor (C) is correct, (D) is wrong.
Final Answer:
The chart with one ring per data series is the Doughnut chart. This is option (A).
