The correct option is A Microwave ovens
Infrared radiation are used in microwaves ovens in electronagnetiic spectrum frequency and energy of microwave is smaller than visible light water contain is required for coobing food in microwave oven almost all food item contain some water contain.Microwaves interact with water molecules all atoms via their electric and magnetic fileds. Temprature of water molecules increases by this these water molecule share this energy with neighbouring food molecules, heating up the food.
