A Hertzsprung-Russel diagram is shown.

A graph with temperature in Kelvin on the x-axis from 40000 to 2500 and luminosity in lumens of the sun on the y-axis. There are labeled areas on the graph with plotted points. The area labeled Supergiants has 3 points, (4900, 14000), (3000, 10000) and (2800, 100000). The area of white dwarfs lies between (35000, .1) and (7000, .0001). The area of red giants run from (6000, 10) to (2600, 100). There is a curve of points, labeled main sequence, between (25000, 10000) all the way down to (2500, .0001).
Which stars tend to have the greatest range of temperatures and the highest luminosities?

red giants
white dwarfs
supergiants
main sequence

Supergiants

They occupy the top of the H–R diagram (highest luminosities) and span a wide temperature range (from hot to very cool), so they show both the greatest luminosities and the largest temperature spread.
