Answer:
Layer A- CORE
Layer B- RADIATIVE ZONE
layer C- CONVECTIVE ZONE
Layer D- PHOTOSPHERE
Layer E- CHROMOSPHERE
Explanation:
The core of the sun is the interior past where nuclear reactions leads to the consumption of hydrogen gas in order to form helium gas. These reactions releases a significantly huge amount of energy that emits from the the surface in the form of visible light and are highly sensitive to both the temperature as well as density.
The radiative zone lies between the core and the convection zone of the sun. From this zone, the energy is released due to the nuclear fusion in its core. This energy is liberated into the space in all direction in the form of electromagnetic radiation.
The convection zone presents the outer-most layer of the sun's interior. It covers a distance from a depth of about 200,000 km up to the sun's surface that is very distinct. In this region, the energy is carried in the form of convections. The light is originated from the surface of this particular zone.
The photosphere is the region that is prominently visible from the earth's surface. This layer has a thickness of about 100 km. The features such as the sunspots (dark), bright faculae, and those granules are clearly observed with the help of telescopes.
The chromosphere is the region in the sun that emits a reddish glowing light due to the burning of super-heated hydrogen. Sometimes, only the red rim is only viewed during the time of total solar eclipse.
