The Type V classification of building construction includes:

• A. Wood frame
• B. Ordinary
• C. Non-combustible
• D. Heavy timber

Answer: (A)

Type V construction is defined by wood-frame construction, using combustible framing members like studs and joists. This category is the one that relies on wood for the primary structural system, which is why it’s the correct choice here.

In contrast, noncombustible construction (Types I and II) uses materials such as concrete, steel, or masonry for the structural frame. Ordinary construction (Type III) features noncombustible exterior walls with some combustible interior elements, so it isn’t purely wood framing. Heavy timber (Type IV) uses large timber members and is designed for greater fire resistance than typical wood-frame construction.
