Question

How is the Sun's magnetic behavior associated with its activity cycle?

A. The magnetic field turns off when the activity cycle turns on.
B. The activity cycle is coordinated with the peak number of sunspots.
C. The activity is independent of the number of solar flares.
D. Solar flares are not coordinated with magnetic storms on Earth.

Answer 1

I believe "B"

Step-by-step explanation:

In the Sun, the flows of hot plasma in the convection zone create the solar magnetic field. This is sustained by nuclear fusion in the Sun. ... The number of sunspots on the sun increase and decrease over time in a regular, approximately 11-year cycle, which is, in fact the solar magnetic activity cycle.
