• B. Thermal energy
• C. Radiant energy
• D. Mechanical energy

Answer: (A)

Verified step by step guidance

1. Understand that a battery stores energy in a specific form before it is converted to other types of energy to power devices.
2. Recall that batteries store energy chemically, meaning the energy is contained in the chemical bonds of the substances inside the battery.
3. When the flashlight is turned on, the chemical energy in the battery is converted into electrical energy, which then powers the light bulb.
4. Recognize that the input energy to the flashlight from the battery is therefore chemical energy, as this is the original form of stored energy before conversion.
5. Note that thermal energy, radiant energy, and mechanical energy are forms of energy that may be produced or used later, but they are not the initial input energy from the battery.
