Explanation:

Sunspots are temporary phenomena on the Sun's photosphere (the visible layer) that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by intense magnetic activity. Solar winds are streams of charged particles (plasma) released from the upper atmosphere of the Sun. Planetary nebulae are glowing clouds of ionized gas expelled from red - giant stars. Coronal mass ejections are large expulsions of plasma and magnetic field from the Sun's corona. Astronomical units are a unit of length used in astronomy. Since the question is about the dark blotches on the Sun's visible surface, the correct term is sunspots.
