Water in an electric kettle gets heated due to

The correct answer is [A] Due to conduction. Water in an electric kettle gets heated primarily due to conduction. When the heating element of the kettle comes into direct contact with the water, thermal energy is transferred through the metal of the element to the water molecules, causing them to vibrate and increase in temperature. This process is a classic example of conduction, where heat is transmitted through direct contact between particles. While convection may play a minor role as the heated water rises and cooler water sinks, and radiation may contribute slightly to the overall heating process, the main mechanism responsible for heating the water in an electric kettle is conduction.
