Which of the following has the greatest wavelength?

From the given figure, we can see that the wavelength is increasing from left to right. For example- the Wavelength of gamma rays is 0.0001 nm, but of radio waves is between 1 cm and 1 mtr.

The figure also demonstrates a zoomed-in version of the visible spectrum, where Purple has the smallest wavelength of 400 nm among the lot.

Coming to the question-

Yellow visible light wavelength = 600 nm
Red visible light wavelength = >700 nm
Infrared radiation = 1000 nm

Hence, OA should be Infrared radiation.
