Which term refers to an eruption of gas from the sun's surface when loops connect in sunspot regions?

• A. Transpiration
• B. Solar flare
• C. Cohesion
• D. Adhesion

Answer: (B)

When magnetic loops in sunspot regions connect and snap into a new configuration, a lot of magnetic energy is released that heats the surrounding plasma and accelerates particles. This sudden release shows up as a solar flare—a bright burst of energy across many wavelengths that can shoot out radiation and particles into space. The term solar flare specifically captures this explosively active, radiative event tied to magnetic activity on the sun’s surface. Transpiration is a plant process of water movement, while cohesion and adhesion describe how water molecules stick to each other or to surfaces. Those ideas don’t describe solar phenomena, so they don’t fit here.
