Which option completes the pattern? (Rotation not allowed)

The correct option is Option 3.

Step-by-Step Explanation:

To determine the missing piece that completes the 2×2 matrix pattern, we analyze the visual symmetry across the horizontal and vertical axes:

1. Vertical Axis Symmetry (Left vs. Right):
- Comparing the top-left quadrant and the top-right quadrant, we observe that the top-right quadrant is a horizontal reflection (mirror image) of the top-left quadrant.
- In the top-left quadrant, the curved arc bulges to the right, a triangle pointing upward is located on the left edge with a horizontal dividing line, and a small circle is positioned to the right of the arc in the upper area.
- In the top-right quadrant, the arc bulges to the left, the circle is on the left of the arc (top-left area), and the upward-pointing triangle is on the right edge.

2. Horizontal Axis Symmetry (Top vs. Bottom):
- Comparing the top-right quadrant to the bottom-right quadrant, the bottom-right quadrant is a vertical reflection (flipped upside down) of the top-right quadrant.
- The triangle on the right now points downward in the bottom-right corner, and the circle moves to the bottom-left area of that square.

3. Determining the Missing Quadrant (?):
- The missing bottom-left quadrant must be the vertical reflection of the top-left quadrant (or equivalently, the horizontal reflection of the bottom-right quadrant).
- Reflecting the top-left quadrant vertically yields:
1. An arc that continues curving to the right.
2. A triangle on the left side flipped upside down (pointing downward into the bottom-left corner with a horizontal line across it).
3. A circle located in the bottom-right area of the square.

Matching these visual elements with the options provided, Option 3 correctly completes the pattern without requiring any rotation.
