Answer 2

Answer: Option A.

Explanation: When you turn on your laptop, you are allowing the electrical energy to flow in the components of the laptop.

Once it is on, you can see that your laptop is generating light (from the screen) and sound (maybe if you are listening to music or something). And as the electricity is passing through the components of the laptop, the components start to raise their temperature, and then you also are generating thermal energy.
