Final answer:
The correct answer is Magnetic (option B). The Sun's structure can be explained by the interaction of gas with the Sun's magnetic field. This field plays a crucial role in the formation of structures like sunspots, solar flares, and coronal loops.
Step-by-step explanation:
The Sun's structure can be explained by the interaction of gas with the Sun's magnetic field. Physicists use the word field to describe the action of forces that one object exerts on other distant objects. In the case of the Sun, its magnetic field plays a crucial role in the formation of structures like sunspots, solar flares, and coronal loops.
For example, sunspots are areas on the Sun's surface where the magnetic field is strong, causing a decrease in temperature and lower levels of energy. Solar flares, on the other hand, are powerful eruptions of energy that occur when the magnetic field lines near sunspots become twisted and release vast amounts of radiation.
