What does the term Electromagnetic Spectrum refer to?

Explanation:
The term Electromagnetic Spectrum refers to the entire range of electromagnetic radiation, from radio waves with the longest wavelengths to gamma rays with the shortest, including visible light, infrared, and ultraviolet. It’s an umbrella for all frequencies and wavelengths, arranged by wavelength or frequency, not just a single portion. The other options name specific parts of this continuum (visible, infrared, ultraviolet), whereas the spectrum covers all of them together, which is why this term is the best answer.
