The observation that most likely led to Jenna’s conclusion about a chemical change occurring in the leftover mashed potatoes is **a change of odor**.
Chemical changes often result in new substances being formed, which can lead to a change in smell. The other options (decrease in temperature, change in moisture content, decrease in mass) may indicate physical changes rather than chemical changes.
