Explanation:

To determine the example of a solid, we analyze each option:

• Option b: Coffee is a liquid as it has a definite volume but takes the shape of its container.
• Option c: A chair has a definite shape and volume, which are key characteristics of a solid.
• Option d: Water is a liquid, similar to coffee, with a definite volume but variable shape.
