Answer
Correct Answer: (iv), (iii), (ii), (i), (v), (vi)
Explanation
Introduction / Context:Construction follows a bottom-up dependency chain. The question demands structural logic from substructure to habitable space.
Given Data / Assumptions:
- Foundation provides base.
- Floor slab is laid on the foundation/subgrade.
- Walls are erected upon the floor/beam system.
- Windows are installed in walls.
- Roof caps the structure.
- Room becomes usable after enclosure.
Concept / Approach:Dependencies: element B cannot exist securely before element A that supports it.
Step-by-Step Solution:1) (iv) Build foundation.2) (iii) Lay floor/ground slab or primary deck.3) (ii) Raise walls.4) (i) Fit windows into wall openings.5) (v) Install roof.6) (vi) The enclosed space is now a room.
Verification / Alternative check:Any ordering with roof before walls/windows is infeasible; room cannot precede enclosure.
Why Other Options Are Wrong:Options placing roof early or windows before walls violate construction dependencies.
Common Pitfalls:Confusing finishing order with structural sequence; assuming “room” is a component rather than the completed space.
Final Answer:(iv), (iii), (ii), (i), (v), (vi)
