The correct response is:
Red stripes reflect red and absorb all other light, as does the blue square with blue; white stripes and stars reflect all wavelengths; and the flagpole absorbs all wavelengths.
This explanation accurately describes how the colors of the flag are observed: the red stripes reflect red light, the blue areas reflect blue light, and the white stripes and stars reflect all visible wavelengths of light. In contrast, the flagpole absorbs all wavelengths, resulting in its black appearance.
