To solve this logical reasoning question, we need to analyze the given pattern and determine which figure completes it. Let’s examine the steps:

1. Look at the pattern in the figure. Notice that it is divided into smaller sections with triangles. The aim is to identify how these sections are structured.
2. The pattern has a consistent arrangement of triangles across the grid. Observe how lines are drawn diagonally and intersect each other.
3. In the missing section, notice that it needs to match the symmetric and consistent placement of lines and triangles in the adjacent sections.

Now, let's analyze the given options to determine which one fits the pattern:

• Option 1: The line and triangle arrangement should be checked for symmetry with the existing pattern.
• Option 2: This should be done similarly.
• Option 3: Evaluate this option as well, focusing on consistent connectivity.
• Option 4: This option aligns correctly with the existing sections. The diagonal and intersecting lines complete the pattern symmetrically.

Based on the above analysis, Option 4 is the correct choice as it fits perfectly to complete the given pattern without any rotation.
