Hint 1 of 2
The paper is transparent, so after folding you see both the original marks and their mirror images together.

Hint 2 of 2
Reflect the holes and lines across the dashed fold line and overlay them on the side that stays put.
Show solution
Approach: reflect across the fold and overlay
- Folding along the dashed line lays one half onto the other; since the paper is see-through, each mark and its mirror image both show.
- Reflect the holes and the zig-zag line across the fold line and combine them with the marks already there.
- The resulting pattern of holes and lines matches choice C.
- So the folded paper looks like C.
