Detailed Solution & Explanation

A pie chart is a circular statistical graphic divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle θi\displaystyle \theta_i and area) is proportional to the quantity xi\displaystyle x_i it represents. The central angle for the i\displaystyle i-th category is calculated as: θi=(xi∑xi)×360∘\theta_i = \left( \frac{x_i}{\sum x_i} \right) \times 360^\circ This representation is best suited for categorical data (nominal or qualitative data), where data is grouped into distinct, non-overlapping categories (such as eye color, nationality, or product brands) to show the relative contribution of each category to the total. Hence, **Option A** is the correct answer.
