Answer:
The answer is B.
Step-by-step explanation:
The convective zone is the outermost layer of the sun. This means that this region would be the least dense zone of the sun. Moreover, the core and the radiative zones are the 'fuel' for the heat and light of the sun emitted by the convective zone in tiny packages called photons. Secondly, the reason the answer is B and not D, is because the energy is transferred the the movement of gas. Also called, CONVECTION. Yeah, that's where the name comes from :)
So, if Sahil were to make the radiative zone, uniform density, we might be cooking. YIKES. Probably what happened to dinosaurs.
If Sahil, makes the entire sun, the density of the convective zone, the SUN would be much, much colder. :)
