The sequence of energy transformations in a closed circuit from the battery begins with chemical energy stored in the battery. When the battery is connected in a circuit, this chemical energy is converted into electrical energy as electrons flow through the circuit. As the electrical energy travels through various circuit components, it may be transformed into heat energy due to resistance in the wires and other components.

Additionally, if the circuit includes devices like light bulbs or LEDs, the electrical energy can also be converted into light energy. This can happen simultaneously with the generation of heat energy. After these transformations, if the circuit is closed and continues to operate, the electrical energy from the battery sustains the flow of electrons, while also converting additional energy into light and heat.

The correct answer captures the complete sequence of these transformations accurately, outlining the initial chemical energy from the battery followed by the subsequent conversions into electrical energy, heat energy, light energy, and back to electrical energy. This comprehensive understanding of energy transformation helps clarify how energy flows and changes form within a circuit.
