The correct answer is - Core<Radiative Zone<Convection Zone<Photosphere<Chromosphere<Transition Zone<Corona
Explanation:
The layers of the sun is comprised of 7 layers, that has 3 inner layers and 4 layers in outermost that are core, radiative zone, convection zone that makes the innermost layer of the sun.
In the outermost layer of sun there the correct order would be photspehere chromosphere, transition zone and corona from inner to outermost layer.
Thus, the correct answer is - Core<Radiative Zone<Convection Zone<Photosphere<Chromosphere<Transition Zone<Corona
