To solve this problem, we need to identify the pattern or sequence logic in the given series of figures and identify which option logically completes it.

Upon examining the provided figures, we notice the following sequence:

1. Each figure contains a consistent arrangement of vertical lines with specific shapes or arrows at their ends.
2. The first figure starts with shapes at the top of lines, followed by alternate downward-pointing arrows.
3. The second figure has alternating upward-pointing arrows and different shapes at the top.
4. The third and fourth figures continue this alternation pattern. The sequence logically alternates between shapes and arrows pointing in different directions.

To logically complete the series, the missing figure should continue this pattern.

By selecting the option with figures that alternate properly, we find that the option with is the correct completion. This option continues the use of alternating shapes and arrows, which follows the established sequence pattern.

Therefore, the correct answer is the figure represented by the first option.
