Question

The figure below shows the spatial arrangement of rooms in a building with access from the exterior, marked as 'entry'. Identify the appropriate diagram showing the access to rooms starting from the entry. \begin{center} \includegraphics[width=0.45\textwidth]{05.jpeg} \end{center}

• A. A
• B. B
• C. C
• D. D

Hint:

In spatial arrangement questions, always start mapping from the entry point. Build connections room by room, then compare with the graph/tree diagrams provided.

Answer 1

The Correct Option is C

Step 1: Identify Entry Point.
\nFrom the building plan, entry is through room \(A\), situated at the bottom center. This serves as our starting node. \n\n \n

Step 2: Direct Connections from \(A\).
\nFrom room \(A\), there are direct connections to: \n- \(B\) (left side), \n- \(H\) (right side), \n- \(I\) (upper side). \n\nTherefore, \(A\) has three immediate adjacent rooms. \n\n \n

Step 3: Connections from Room \(I\).
\nFrom room \(I\), connections extend to: \n- \(C\) (left), \n- \(G\) (right), \n- \(E\) (upper side). \n\n \n

Step 4: Additional Connections.
\n- Room \(C\) further connects to \(D\). \n- Room \(G\) further connects to \(F\). \n- Room \(E\) connects upward but does not lead to any other rooms. \n\nThis establishes a hierarchical structure, expanding upwards and sideways. \n\n \n

Step 5: Match with Provided Diagrams.
\n- Diagram (A) depicts a linear sequence, which is inconsistent. \n- Diagram (B) illustrates a chain with a single side extension, failing to represent the branching pattern. \n- Diagram (C) shows a central entry point leading to \(B, H, I\), with subsequent branches to \(D, E, F, G\). This aligns perfectly with the identified connections. \n- Diagram (D) presents a star configuration with uniform distribution, which does not reflect the actual connectivity. \n\n \n

Final Answer: \n\[\n\boxed{\text{(C) Diagram C}}\n\]
