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 and the flagpole interact with light. The red and blue sections of the flag reflect their respective colors and absorb others, while the white sections reflect all wavelengths of light. The black flagpole absorbs all wavelengths of light, making it appear black.
