The Correct Option is A
Solution and Explanation
Step 1: Analyzing the 3D structure from Figure A.
The assembly consists of five identical cubes and one smaller cube. Viewing the assembly from direction \( Y \) means observing the structure from the left side as indicated in Figure A.
Step 2: Determining the planar projection.
- The smaller cube is positioned at the top and to the left in the 3D structure.
- The projection from \( Y \) aligns with the arrangement of cubes seen from that angle.
- Comparing the options, only option (1) accurately represents the planar projection from \( Y \).
Step 3: Conclusion.
The planar image of the assembly viewed from direction \( Y \) is \( {(1)} \).
