Show answer and explanation
Correct answer: (B) (ii)
Explanation
By projecting the isometric 3D models in Panel II onto the vertical and horizontal reference planes:
- Orthographic projection of structure (ii) from the front yields the exact arrangement of rectangular and stepped blocks shown in the front view of Panel I.
- Orthographic projection from above matches the boundary profile and internal line boundaries of the top view in Panel I.
Structures (i), (iii), and (iv) fail to produce the required top view and step transitions. Therefore, structure (ii) is the correct choice, matching option (B).
