A. long wavelength; small
Diffraction is the greatest whenever the gap where the wave is passing through is smaller. This gap property will make the wave to "curve" reaching a more wider area, the smallest the gap is, more the wave will curve, spreading more widely. The light would propagate more rather then being concentrated on one focus. The wavelength is also something that affects diffraction. Whenever the wavelength is longer, the wave will have more time to spread sideways after diffraction.
Organisms obtain energy from the foods
Dry air might be the answer but honestly I’m not sure if it is
