Detailed Solution & Explanation
When representing the breakdown of a total amount (such as total cost) into its constituent components or 'heads' (e.g., raw materials, labor, overheads), the primary objective is to show the relative contribution or proportion of each part to the whole. A pie chart (or circle diagram) is specifically designed for this purpose, as the entire circle represents the total cost (100%), and the angular sectors represent the individual cost heads proportional to their values. While multiple line charts are used for time-series data of multiple variables, and bar graphs can compare individual categories, a pie chart is the most appropriate for representing the composition of a total. Hence, **Option A** is the correct answer.
