I think the answer is D, the radiative zone because, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation. in other words, Energy is in the core but it takes radioactive waves to make it reach earth.
I don't think it's A, B C, because,
the corona has to do with the light of the sun
gamma zone is an example of radiation
the core is the base of the energy, where it's all stored
radiative zone makes it reach earth
That would be the choice I would choose. I hope this helps you.
The sun and the planets formed together 4,6 billion years ago from clouds of gas and dust called the solar nebula
The intrusion of magma along a bedding* plane is called a Batholith. The reason it would be Batholith is because it comes from a Greek Root word that stands for "<u>depth"</u>. Which would stand for what happens down their in the earth which would be "Batho-lith".
