It would be A: Have a greater height.
The higher the wave the higher the energy!
Tbh ! All of them have lens but I would go with B.) Smart Phone
Hope This Helps !!!
Ok so B would be the best surface to reflect heat energy as it's polished and does not disturb the wave of energy like the others would. Also in therms of colour it's better because it's a lighter colour than navy ( the darker colour of the spectrum ). This matters as darker colours absorb light where light colour reflect it.
Hope this helps :).
