The mineral from the given options is sand.
To determine which of the following options is a mineral, we need to understand what qualifies as a mineral. A mineral is a naturally occurring, inorganic solid with a specific chemical composition and a crystalline structure.
Now, let's analyze each option:
1. Sand: Sand is not a mineral. It is a granular material composed of small pieces of rock and mineral fragments.
2. Oxygen: Oxygen is a chemical element but not a mineral. Minerals are typically compounds or substances, whereas oxygen is a single element.
3. Wheat: Wheat is not a mineral. It is a cereal grain and a plant product.
4. Plastic: Plastic is not a mineral. It is a synthetic, man-made material formed from polymers.
Out of the given options, none of them are minerals.
