Select a suitable figure from the four alternatives that would complete the figure matrix.

Step 1: Observe the matrix column-wise.
Step 2: In each column:
• The number of diagonal lines remains constant.
• The number of dots increases systematically from top to bottom.
Step 3: In the third column: Top → 3 dots, Middle → 4 dots
Step 4: Therefore, the bottom figure must contain 5 dots with the same diagonal line pattern.
Step 5: Only option (d) satisfies this condition.
