How is energy transferred from the core of the Sun to its outer layers?

In the core, nuclear reactions combine hydrogen atoms to form helium, releasing vast amounts of energy in the process. The energy released then begins to move outward, towards the outer layers of the Sun. The radiative zone is just outside the core, which has a temperature of about 7 million degrees Celsius.

It's lithogenous i believe of course i looked it up.

The sun's parallax would be 180 degrees, greater than which you can't get.  so a. would be your anwser
