Image 4, because of two observations:
- within a single image, there are no crossed lines (T's are okay)
- in all pairwise overlaps, no line in one image is crossed twice by the other image
Image 4 is the only option that meets both criteria. (3 and 5 cross themselves, and 1, 2, 3 cause double-crossings in the overlap.)
4. The result of the ex-triangle is a side rearrangement. Only 4 complies with that. Then sides get to multiply and reduce until they get to another triangle.
My Answer is 5.
Above Totally 9 Images, So I splited into 3 section.
3rd image have 3 lines,
6th image have 4 lines and
so, 9th image(blank) should have 5 lines.
Answer Option Images Have only one Five Line Image that is 5th image.so, MY Answer is 5 image could replace blank(9th) one.
I think it's:
1. Because there are multiple reflections, especially given the last clue. I can't figure the reasoning, but early on I saw that 6 & 7 merged resulted in a common copy icon. After overlapping and tilting 3 & 4, there's a double X shape. That leaves 1, 2, & 5 orphaned in this explanation.
