Question
What causes Sunspots and why do they appear dark?
Sunspot - Wikipedia
a
The Sun's magnetic fields cause plasma on the surface to cool down and turn dark
b
Extreme solar winds push the plasma to different locations, causing it to change color
c
Larger than normal fusion reactions occur in the core, causing dark sunspots to bubble up to the surface.

The correct answer is:
**a. The Sun's magnetic fields cause plasma on the surface to cool down and turn dark.**
Sunspots are regions on the Sun's surface that are cooler than their surroundings due to intense magnetic activity. These magnetic fields inhibit the convection process of plasma, which leads to a decrease in temperature in these areas. Since they are cooler than the surrounding areas, they appear darker when observed, hence the name "sunspot."
