Answer 1

Answer: (A), (C)

The correct options are
A

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

C

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

In a pie chart, data is quantified using areas of segments. Because area of a segment of a circle depends on the angle subtended by the same arc at the centre of the circle, even this can be used to find information of the desired quantity.
