Question

Two views of a 3D object are shown on the left. Which of the option(s) is/are the \textbf{same object?}

• A. A
• B. B
• C. C
• D. D

Hint:

For 3D object matching: \begin{itemize} \item Rotations preserve structure; reflections do not, \item Track unique bends or offsets as anchors, \item Compare one arm at a time systematically. \end{itemize}

Answer 1

The Correct Option is D

Step 1: Carefully study the two given views of the original object. Note the relative positions, lengths, and orientations of all protruding arms. \bigskip Step 2: Identify invariant features that do not change under rotation: \begin{itemize} \item Number of arms, \item Relative angles between arms, \item Distinctive bends or offsets. \end{itemize} \bigskip Step 3: Compare each option with the given object by attempting mental rotation (without reflection). \bigskip Step 4: \begin{itemize} \item Options A, B, C: Each fails to match at least one arm orientation or relative bend when rotated — not the same object. \item Option D: Matches all arm positions and bends exactly after a suitable rotation — correct. \end{itemize} \bigskip Final Answer: \[ \boxed{D} \] \bigskip
