(1 point) they are caused by outward fluctuations of the suns magnetic field. they tend to occur during active periods of the solar cycle. they appear as dark spots on the suns surface. they appear as bright spots on the suns surface.

Explanation:

Sunspots, solar flares, and coronal mass ejections are solar - activity phenomena. Solar activity is related to the sun's magnetic field fluctuations and the solar cycle. Sunspots are dark spots, while solar flares and coronal mass ejections are not just dark or bright spots in the same sense. They are caused by the outward fluctuations of the sun's magnetic field and tend to occur during active periods of the solar cycle.

Answer:

They are caused by outward fluctuations of the sun's magnetic field.
They tend to occur during active periods of the solar cycle.
