Use the diagram to answer the question.
The Hertzsprung-Russell Diagram shows the spectral class of stars across the top, the temperature in Kellvin of stars across the bottom. The luminosity of stars, with the luminosity of the Sun equal to one, on the right, and the absolute magnitude of stars on the right. Blue giants, red supergiants, red giants, main sequence stars, the Sun, and white dwarfs are shown on the diagram.
Which type of star is in spectral class K and has a luminosity of 106?

To answer the question, we need to locate the point on the Hertzsprung-Russell Diagram that corresponds to a spectral class of K and a luminosity of 10^6.
Looking at the answer choices, we can eliminate blue giants, red giants, and white dwarfs because they are not in spectral class K. This leaves us with the option of a red supergiant.
Therefore, the correct answer is a red supergiant.
