The correct answer is rooted in understanding the structure of a pier and beam foundation. In this type of foundation, piers are crucial components that support the structure above. These piers are typically made of concrete and are either drilled or formed into the ground to provide a stable base.

Piers serve the purpose of transferring the load of the home down to the soil, providing elevation above the ground which is important for moisture protection and stability. They are strategically placed to ensure that the weight distribution is even, preventing settlement issues and allowing for proper drainage.

The other components mentioned, such as beams, floor joists, and subfloor, play different roles in the overall framework. Beams connect the piers and serve as horizontal supports for the floor joists, which distribute the weight of the flooring itself. The subfloor is the layer that sits on top of the floor joists, providing a surface for the finished flooring material. While all these components work together, it is the piers that specifically consist of the concrete formations in the ground, making them the distinct answer for this question.
