Which processes transfer energy from the core to the photosphere? a)radiation, then friction b)convection, then conduction c)radiation, then convection d)conduction, then friction

The answer is C. Radiation then convection
The energy from the core propagates through the radiative zone, whilst in the convection zone the energy moves mainly through rising current of heated gas onto the convection zone which carries the energy toward's the surface of the Sun.

The answer is radiation, then convection

Yes
