Correct Answer: Option A - A full-disk view of the sun, showing sunspots on the photosphere and a close-up of solar granulation (bottom) we see as the glowing surface of the sun-the photosphere. The temperature of the photosphere is around 5,500ºC (about 9000ºF). The photosphere is much cooler than the sun's core, which has a temperature well above 10 million degrees.
