Explanation:

5.4

Iron filings are magnetic, which is a physical property. Flammability is a chemical property. Iron filings are not soluble in water.

When sand and water are mixed, they form a mixture. In a mixture, the physical properties of the individual components (sand and water) remain the same.

Mixtures can indeed occur between different states of matter. For example, air (gas - gas mixture), salt - water (solid - liquid mixture), smoke (solid - gas mixture) etc.

Answer:

A. Iron filings are magnetic.
