Which option lists the electromagnetic spectrum order from longest wavelength to shortest?

Explanation:
The main idea is ordering the electromagnetic spectrum by wavelength from longest to shortest. Wavelength and energy are inversely related: as you move from radio waves toward gamma rays, the wavelengths get shorter and the photons become more energetic. So the sequence from longest to shortest is Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma. This matches the given order, with radio first and gamma last. Other options start with gamma or place bands out of their correct relative order, which doesn’t reflect the decreasing wavelength.
