Which part of the Sun is visible during a solar eclipse?

During a solar eclipse, the part of the Sun that is visible is the corona, which corresponds to option [B]. The corona is the Sun’s outermost atmosphere, extending millions of kilometers into space. Normally, it is obscured by the much brighter photosphere, the Sun’s visible surface layer. However, during a total solar eclipse, when the Moon aligns perfectly between the Sun and Earth, it blocks out the photosphere, allowing the corona to become visible from Earth. The corona appears as a halo of pearly white light surrounding the dark silhouette of the Moon. Its delicate structures, such as streamers, loops, and prominences, are visible due to the faint light emitted by ionized gases in the corona. Observing the corona during solar eclipses provides valuable insights into the Sun’s outer atmosphere and helps scientists study phenomena such as solar wind, solar flares, and magnetic fields that extend into space.
