Sudden, intense explosions that result in changes in brightness when magnetic energy is released.
A
Prominences
B
Solar Flare
C
Sunspot
D
Photosphere
Explanation: 

Detailed explanation-1: -A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours.

Detailed explanation-2: -The magnetic field lines near sunspots often tangle, cross, and reorganize. This can cause a sudden explosion of energy called a solar flare. Solar flares release a lot of radiation into space. If a solar flare is very intense, the radiation it releases can interfere with our radio communications here on Earth.

Detailed explanation-3: -Solar flares occur when magnetic energy builds up in the solar atmosphere and is released suddenly. These outbursts are intrinsically linked to the solar cycle-an approximately 11-year cycle of solar activity driven by the sun’s magnetic field.

Detailed explanation-4: -During such an event, the ions and electrons become decoupled from each other and begin to move perpendicular to the sun’s magnetic field lines, creating an unstable energy vacuum through the interplay of electric and magnetic fields.

Detailed explanation-5: -The ionizing radiation released during solar flares includes x-rays and gamma rays. These rays of ionizing radiation can damage satellites because they are in space and are not protected by the Earth’s atmosphere.

Detailed explanation-6: -Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs).
