The statement that best describes common framing systems in residential construction is that wood frame exterior walls are either load-bearing or non-load bearing. This description accurately reflects traditional framing practices, whereby residential constructions utilize wood framing due to its versatility, availability, and structural properties. Load-bearing walls support the weight of the structure above them, while non-load bearing walls provide partitioning and do not carry structural loads. The other options present trends or requirements that are either too specific, inaccurate, or not widely applicable across the current construction landscape. For example, while metal studs may be used in specific contexts or projects, they are not the predominant choice for all framing needs in residential buildings. Moreover, indicating that two-by-four exterior walls are prevalent solely for energy efficiency overlooks the numerous factors involved in framing decisions. Lintels, while a critical component of framing above openings, do not encompass the full scope of framing systems. Thus, the correct portrayal of common framing practices lies in recognizing the functions and classifications of wood frame exterior walls.
