ChatGPT said:
Yes. Treat the two arrows in each row as two moves of a small “marker” that starts in the center of the square:
-
If the marker ends in the interior, you see it as a small filled square (that’s why ↑ then ↓ returns to the center → option A, matching the middle row).
-
If the marker ends up pushing out through an edge, it creates a notch/opening on the corresponding edge.
For the last row: ↓ then ↓ moves the marker down to the edge and then out through it, so you need the square with an edge opening — that corresponds to D.
Answer: D
