Answer:

A. Light from sunspots

Step-by-step explanation:

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.

The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.
