Solution
The correct option is A Red
Red coloured light (620 - 720 nm) has largest wavelength in white light spectrum and the violet light at the other end has the least wavelength (400 - 440 nm). Rest all the constituent colours have intermediate range of wavelength lying between these two upper and lower limits of wavelengths.
