Correct option is D)
All elements and compounds are homogeneous, as they are pure substances. A mixture can be homogeneous or heterogeneous. So, options A, B and C are correct statements.
Air is a homogeneous mixture as the components are spread uniformly throughout the mixture. So, option D is an incorrect statement.
