The correct answer is D) light.

The electromagnetic spectrum encompasses a wide range of wavelengths, from radio waves to gamma rays. The visible portion of this spectrum, which is perceived by the human eye, is commonly referred to as visible light. This range includes the colors of the rainbow, from red (longer wavelengths) to violet (shorter wavelengths).

Infrared radiation has longer wavelengths than visible light and is associated with heat. Radiowaves and microwaves have much longer wavelengths and are used for communication and heating (like in microwave ovens), respectively. None of these are visible to the human eye. The visible spectrum lies between approximately 380 and 750 nanometers.
