  1. Stabilizing soil pH

  2. Enhancing water retention

  3. Providing nutrients

  4. Plastic when moist and hard whe fired

The correct answer is: Plastic when moist and hard whe fired

Clay in soil serves several functions, such as improving the texture of the soil and increasing water retention capacity. However, its main function is being plastic when moist and hard when fired. This property allows clay to hold its shape and structure, providing stability to the soil and preventing erosion. The other options, while they may be true to some extent, are not the primary or most significant function of clay in soil.
