It is electromagnetic wave, therefore the correct choice is

Q. The condition under which a microwave oven heats up a food item containing water molecules most efficiently is :

Infra-red waves produce heating in a microwave oven

The frequency of the microwaves must match the resonant frequency of the water molecules

The frequency of the microwaves has no relation with natural frequency of water molecules

Microwaves are heat waves, so always produce heating

It is electromagnetic wave, therefore the correct choice is
