The example of a physical change from your options is **dry ice becoming vapor**.
This process, known as sublimation, involves the dry ice (solid carbon dioxide) turning directly into carbon dioxide gas without passing through a liquid state, which is a physical change rather than a chemical change.
The other examples involve chemical changes (the smell of rotten eggs is due to the production of sulfur compounds, while the creation of table salt involves a chemical reaction between sodium and chlorine) or are related to properties (the green color of the Statue of Liberty is due to the oxidation of copper).
