The correct answer is: A. Kneading
Kneading is the process of mixing clay, water, and other ingredients to make brick. It is a very important step in the brickmaking process, as it helps to ensure that the clay is evenly mixed and that there are no air bubbles. Kneading also helps to develop the clay’s plasticity, which is its ability to be shaped and molded.
The other options are incorrect because they do not describe the process of mixing clay, water, and other ingredients to make brick.
B. Moulding is the process of shaping the clay into bricks. It is done by pressing the clay into a mold or by hand.
C. Pugging is a process of compacting the clay to remove air bubbles and make it more dense. It is done by forcing the clay through a pug mill, which is a machine with a series of rollers.
D. Drying is the process of removing water from the clay. It is done by exposing the clay to air or by heating it.
