Which of the following is NOT an example of ceramics?

Explanation:
Ceramics are inorganic, non-metallic solids formed by shaping mineral-based materials and then firing them to high temperatures, creating rigid, heat-resistant networks. Clay and porcelain fit this because they come from mineral clays and silica and are fired to become hard, durable materials. Brick is also a ceramic for the same reason—it’s made from fired clay. Wood is an organic polymer made mainly of cellulose, hemicellulose, and lignin. It isn’t created by firing into an inorganic network, and it behaves differently under heat (it chars or burns and is moisture-sensitive). So wood is not a ceramic.
