The correct choice that accurately identifies the components responsible for energy transformation in Tim's toy car is:
**A. Solar panel: Converts light energy into electrical energy. Motor: Converts electrical energy into mechanical energy.**
**Explanation:**
- **Solar Panel:** This component captures light energy from the sun and converts it into electrical energy through the photovoltaic effect.
- **Motor:** This component takes the electrical energy provided by the solar panel and transforms it into mechanical energy, which drives the car's movement.
The other options contain inaccuracies regarding the functions of the components listed, particularly the roles that switches, wires, and wheels play in energy transformation, which don't align with the basic principles of energy conversion in solar-powered systems.
