Answer to Question 1

Energy is produced in the core. It enters the radiative zone, where it moves as radiation. As it gets further out from the center, the gas gets less ionized and so more opaque to radiation. In this region the energy moves by convection, with hot gas physically rising through the Sun. When it reaches the surface, or photosphere, the low density makes the Sun transparent, and the energy escapes as light.

Answer to Question 2

C
