Step 1: Understanding the Question:
The matrix has three filled boxes and one empty box. We must find the figure that fills the empty box.
Step 2: Read each box:
Top left has 1 circle, top right has 3 circles, bottom left has 2 circles, bottom right is unknown.
Step 3: Look for the multiplying rule:
Going from the left box to the right box, the number of circles is multiplied by 3 (1 × 3 = 3). The same rule must hold in the bottom row: 2 × 3 = 6 circles.
Step 4: Match with the options:
Option 4 shows 6 circles (two columns of three). Options 1, 2 and 3 show 3, 4 and 5 circles.
Final Answer:
The missing figure is option 4.
\[ \boxed{\text{Option 4}} \]
