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."
