None of the above

Detailed explanation-1: -The convection zone is the outer-most layer of the interior. It extends from a depth of 200, 000 km up to the visible surface of the Sun. Energy is transported by convection in this region.
Detailed explanation-2: -Inside the Sun, conduction is ineffective (the Sun is not solid). Energy is transported by convection in the outer regions of the Sun (the outer 30 percent, or so). Energy is transported by radiative diffusion in the inner regions of the Sun (the inner 70 percent).
Detailed explanation-3: -The energy travels through the radiative zone and the convective zones of the Sun, through other layers, all the way to the Sun’s surface (photosphere), outward into space, eventually reaching Earth. The Sun will continue to make energy for another 5 billion years, when it will run out of hydrogen atoms to fuse.
