Correct option is E)

A homogeneous mixture has the same uniform appearance and composition throughout.  

A heterogeneous mixture consists of visibly different substances or phases. A salad with lettuce, cheese, seeds, tomatoes, broccoli, and other vegetables is an example of a heterogeneous mixture.

solution and milk is a homogeneous mixture has uniform composition throughout.

Sand and water make a heterogeneous mixture as sand is insoluble in water and the mixture has localized regions with different properties.

Pure iron is not at all a mixture. It is a  pure form of an element and can not be classified as homogeneous or heterogeneous mixture.
 
Hence, option E represents a false statement regarding mixtures.
