solar wind
B
solar flares
C

D
sunspots
Explanation: 

Detailed explanation-1: -Sunspots: One interesting aspect of the Sun is its sunspots. Sunspots are areas where the magnetic field is about 2, 500 times stronger than Earth’s, much higher than anywhere else on the Sun. Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases.

Detailed explanation-2: -A sunspot is a cooler, and therefore darker, region of the Sun’s photosphere caused by a solar magnetic disturbance. Strong, dense magnetic fields generated by circulating plasma sometimes become entangled and surge through the photosphere, creating the sunspot.

Detailed explanation-3: -Sunspots, indicators of disturbed magnetic fields, are the most common features seen in the photosphere. Sunspots are generally surrounded by lighter areas called faculae.

Detailed explanation-4: -Photosphere. The fifth layer is the visible surface where sunspots appear.

Detailed explanation-5: -Sunspots and the solar cycle During the solar maximum, many sunspots are found along mid-latitudes (approximately 30 degrees north and 30 degrees south). Then, sunspots gradually move toward the equator, where few are found during the solar minimum. Sometimes, no sunspots are visible during the solar minimum.
