The correct option that highlights the difference between a pure substance and a mixture is:
**A mixture can be physically separated while a pure substance cannot.**
**Explanation:**
- A **pure substance** is made up of only one type of particle and has consistent properties throughout. It cannot be separated into simpler substances by physical means. Examples include elements (like gold) and compounds (like water).
- A **mixture** consists of two or more substances (elements or compounds) that are physically combined and can be separated by physical means, such as filtration or distillation. Examples include air, salad, and saltwater.
