D Correct answer
Explanation

Sunspots are temporary, darker areas on the Sun's photosphere caused by intense magnetic activity that inhibits convection, making those regions cooler (about 3000-4500 K versus 5800 K for the surrounding photosphere). Solar flares are sudden, intense bursts of radiation. 'Sun shadows' and 'solar shades' are not real solar phenomena.
