4. Core

Sunspots are associated with regions of increasing magnetic field. It is visible on the photosphere.

Explanation:

The region of the Sun that is visible to us is the photosphere. It is the lowermost layer of the solar atmosphere. This is the layer where the energy from the interior of the Sun bubbles up and is released as visible light.

One hypothesis is that sunspots are created by changes in magnetic fields in the Sun. Sunspots usually occur in pairs over regions of intense magnetic activity.

Hope the helps and have a nice day!!
