• A. System
• B. Structural assembly
• C. Subassembly
• D. Framework

Answer: (B)

Think about a roof or floor as a single, load-caring unit formed by connecting multiple parts so they work together. The phrase that fits this idea is structural assembly, which emphasizes that the pieces are designed to function as one cohesive whole. A system is broader and can include non-structural parts or cover various functions, not just a unified structural unit. A subassembly is only a portion that will become part of a larger whole, not the completed structural unit itself. Framework describes the basic supporting skeleton, but it doesn’t necessarily convey that the set is a fully integrated structural unit like a roof or floor. So the term that best captures an engineered collection of interconnected components forming a cohesive structural unit is structural assembly.
