Look at the graph below. (5 points) The HR diagram is shown with Absolute Brightness on the y-axis from negative ten to fifteen and Surface Temperature on the x-axis from 40,000 to 2,500 Kelvin. There are several dots plotted between ten and fifteen absolute brightness and 10,000 to 2,500 degrees Kelvin labeled Supergiants. There are several dots plotted between negative 1.5 and three absolute brightness and 7,500 to below 2,500 degrees Kelvin labeled Giants. There are several dots plotted between ten and fifteen absolute brightness and 30,000 to 15,000 degrees Kelvin labeled Dwarfs. Down the middle, there are several dots plotted diagonally from 40,000 and 2,500 Kelvin, and negative ten to positive fifteen are labeled Main Sequence. Label A points to a dwarf star at 15,000 K and 10 absolute brightness. Label B points to a main sequence star at 3,700 K and 10 absolute brightness. Label C points to a main sequence star at 30,000 K and negative 10 absolute brightness. Label D points to a supergiant at 8,500 K and negative five absolute brightness. Which statement is true about Star A? It is red in color. It is yellow in color. It is four times brighter than the sun. It is five times dimmer than the sun.
