Correct answer: D
Explanation:
Look at the puzzle by counting the total number of diamonds in each picture.
The rule can be used by columns:
Column 1: 4, 3, 5
Column 3: 5, 4, 6
In each column, the middle picture has one fewer diamond than the top picture, and the bottom picture has one more diamond than the top picture.
Apply this to the second column:
3, 2, ?
So the missing picture should have 4 diamonds.
The same rule can also be used by rows:
Row 1: 4, 3, 5
Row 2: 3, 2, 4
Row 3: 5, ?, 6
In each row, the middle picture has one fewer diamond than the left picture, and the right picture has one more diamond than the left picture.
So in Row 3, the missing middle picture should have 4 diamonds.
Only Option D has exactly 4 diamonds.
Therefore, the correct answer is D.
