• C. In a pie chart, only the angle subtended by the arc at the center gives us the desired quantity.
• D. None of these.

Answer 1

The correct option is A

In a pie chart, the area as well as the angle subtended by the arc at the center gives us the desired quantity.

In a pie chart, data is obtained using areas of segments. Area of a segment of a circle depends on the angle subtended by the arc at the centre of the circle. Hence, smaller the central angle, smaller the data it represents.
