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.
From the building plan, entry is through room \(A\), situated at the bottom center. This serves as our starting node.

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

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

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

Step 5: Match with Provided Diagrams.
- Diagram (A) depicts a linear sequence, which is inconsistent. - Diagram (B) illustrates a chain with a single side extension, failing to represent the branching pattern. - 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. - Diagram (D) presents a star configuration with uniform distribution, which does not reflect the actual connectivity.

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