Explanation:

The Indus Valley Civilization used oven - baked bricks as a main building component for their houses. These bricks were durable and helped in constructing houses that could cope with the harsh sun and heat. Threshed reeds are more for thatching or other non - main building structural uses, joints intended in timber are not a main component of Indus Valley houses, and concrete was not used in that civilization.

C. Oven - baked bricks
