Answer: D
How to work it out
Each hole goes through both layers, so it appears twice when unfolded: once where it was punched and once mirrored across the vertical fold line.
Why the other options are wrong
- A: One punched hole has no mirror partner. Every hole goes through both layers, so every hole appears twice.
- B: This shows only the mirrored holes. The holes as punched are still on the paper, so they should be there too.
- C: This shows only the holes as punched. Each goes through both layers, so each needs a mirror partner across the fold line.
- E: The partner holes have slid along the fold line. A mirror partner sits directly opposite its hole, at the same distance from the fold.
