Answer: The correct answer is option C.
Explanation:
Electrical energy is an energy possessed by the electrical charges in motion.
Heat energy is an energy due to the motion of particles like atoms, ions etc in solid , liquid and gases .
In an electric kettle:
Electric energy → Heat energy (Law of conservation Energy)
In an electric kettle electric energy is changing into heat energy which results in heating up of water present in side it.The electric energy from the power source is transforming into heat energy which gets transferred to water molecules.
Hence, the correct answer is option C.
