Step 1: Understand the puzzle.
We are combining two blocky hexagonal structures. The left figure has red + navy coloring, while the right figure has green + orange. The task is to visualize the merged figure.
Step 2: Overlay the colors.
- From the first figure: red and navy regions.
- From the second figure: green and orange regions.
When combined, the cube should display all four colors (red, green, navy, orange).
Step 3: Compare with answer options.
- Option (A): Only shows partial green + red, missing full orange overlays.
- Option (B): Dominated by navy + green, missing red.
- Option (C): Shows red + green + orange + navy balanced, consistent with overlaying both original figures.
- Option (D): Misaligned orientation; color placement differs from required overlay.
Step 4: Conclude.
The correct merged figure is option (C).
Final Answer:
\[
\boxed{\text{(C)}}
\]
