Answer:

c. rotary kiln

Explanation:

In the manufacture of cement, the dry or wet mixture of calcareous (calcium-containing) and argillaceous (clay-containing) materials is typically burnt in a rotary kiln. This type of kiln provides the necessary high temperatures and controlled environment to facilitate the chemical reactions that form clinker, the key ingredient in cement.
