The answer is 'D' option, 'All of the above'. It is so because Air is not visible because it neither absorbs nor reflects light, it transmits whole of light. Dust particles in air is visible as they reflect light. Air is almost transparent substance. It is not dust to be visibile. It is air, it is completely transparent.
