C. It was so wide that the air underneath it held it up

Explanation:

Anaximenes claimed that the flat disk of the Earth was in the middle of a cosmos filled with air. Anaximander explains how the four elements of ancient physics (air, earth, water, and fire) are formed, and how Earth and terrestrial beings are formed through their interactions. Air felted to create the flat disk of the earth, which he said was table-like and behaved like a leaf floating on air.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
