Which of the following is NOT a Type II exterior wall classification?

Explanation:
Type II exterior walls are noncombustible; they’re built with noncombustible materials for the wall system and usually have noncombustible framing. Unreinforced masonry, reinforced masonry, and tilt-up panels all fit that noncombustible approach. Wood frame, on the other hand, uses timber as the structural material, which is combustible, so it falls under a different construction type. In most codes, wood-frame buildings are Type V. So the exterior wall option that is not a Type II exterior wall classification is the wood frame option.
