The following graphs relate the amount of hydrogen (shown as light-blue regions) and helium (shown as light-purple regions) within the Sun at three different moments in time. On each graph, the horizontal axis denotes the fraction of radius (distance from the center), and the vertical axis denotes the percentage of mass (the relative amounts of hydrogen and helium). Match each graph to the appropriate evolutionary stage of the Sun.
