A to D, because something must be connected to the other terminal of the battery and the other terminal of the lightbulb in order to complete the circuit.

Chemical to electrical to radiant, because the energy is stored as chemical energy in the battery, then it is converted into electricity, and finally it is converted into radiant energy in the lightbulb.
