To solve this non-verbal reasoning question, we need to identify the pattern in the sequence of figures and select the appropriate figure to replace the question mark (?).

1. Observe the series of figures: each figure has an octagonal outline with increasing number of intersecting lines at the center.
2. The pattern shows a sequence where each new shape adds one additional intersecting line:
   1. The first figure has one line,
   2. The second figure has two lines forming a cross,
   3. The third figure has three lines crossing each other,
   4. The fourth figure has four intersecting lines.
3. Following this pattern, the next figure should have five intersecting lines. This establishes a consistent incremental pattern.

From the provided options, we select the figure that contains five intersecting lines. Here it is:

Therefore, the correct answer is the figure that follows the established pattern, increasing the number of intersecting lines to five.

This solution is based on identifying the pattern of line increment and selecting the corresponding option that fits this pattern.
