Which of the following is NOT a common foundation type?

Explanation:
Floating foundations aren’t a common choice for typical residential construction. The usual foundation types you’ll encounter are slab-on-grade, where a concrete slab sits directly on prepared ground; a perimeter foundation, with a continuous wall around the edge that supports a crawlspace or basement; and a basement or cellar, providing usable space below grade supported by foundation walls. A floating foundation, like a raft or mat system used to spread loads on weaker soils, is more specialized and less commonly used in standard OCFA scenarios due to its complexity and soil requirements.
