A Correct answer
Explanation

Sunspots are temporary darker areas on the photosphere (visible surface) of the Sun caused by concentrated magnetic field activity. They appear darker because they are cooler (around 3,000-4,500 K) than the surrounding areas (about 5,800 K). Red giants, black holes, and neutrons are unrelated astronomical concepts.
