Let me carefully analyze the pattern in the grid of 3×3 squares.
Each circle contains a 3×3 grid of black (■) and white (□) squares.
There are 8 given grids, arranged in 2 rows of 4, and the 9th (bottom-right) is missing — marked with “?”.
We need to find which of options A, B, or C fits the pattern.
Let me count the number of black squares in each grid:
Row 1:
1. Grid 1: Let's count black squares:
Row1: ■ ■ ■ → 3
Row2: ■ □ ■ → 2
Row3: ■ ■ ■ → 3
Total = 3+2+3 =
8
2. Grid 2:
Row1: ■ ■ ■ → 3
Row2: □ □ □ → 0
Row3: ■ ■ ■ → 3
Total = 3+0+3 =
6
3. Grid 3:
Row1: □ ■ ■ → 2
Row2: □ □ □ → 0
Row3: ■ ■ □ → 2
Total = 2+0+2 =
4
4. Grid 4:
Row1: □ ■ □ → 1
Row2: □ □ ■ → 1
Row3: □ □ □ → 0
Total = 1+1+0 =
2
So row 1 black counts: 8, 6, 4, 2 → decreasing by 2 each time.
Now row 2:
5. Grid 5:
Row1: ■ □ ■ → 2
Row2: ■ □ ■ → 2
Row3: ■ ■ ■ → 3
Total = 2+2+3 =
7
Wait — maybe I miscounted. Let me double-check each carefully using zoom.
I'll use the image_zoom_in_tool to get precise counts.
