A club wants to display how its total yearly expenditure of ₹1,20,000 was shared among five heads such as rent, salaries and repairs. Which display is best suited to that purpose, and why?

The question is about the PARTS of one whole, and that is exactly what a pie chart shows: the sectors add to 360° just as the five amounts add to ₹1,20,000, so each share can be read at a glance. A line graph is for a quantity changing over time, and the five heads have no natural order to run along an axis. A histogram needs numerical classes of a definite width, whereas rent and repairs are named categories, not intervals. A pictograph could certainly show the five amounts, but it displays them side by side without showing each as part of the whole.
