Identify the figure given in the options which when put in place of ? will logically complete the series.

To identify the correct figure that completes the series, let us observe the pattern of arrows in each step:

1. First frame: Contains 1 vertical arrow pointing upwards (↑).

2. Second frame: Contains 2 vertical arrows with alternating directions — the first arrow points upwards (↑) and the second arrow points downwards (↓).

3. Third frame: Contains 3 vertical arrows with alternating directions — upwards (↑), downwards (↓), and upwards (↑).

Following this logical sequence:

• The number of arrows increases by 1 in each step (1, 2, 3, 4...). Therefore, the fourth frame must contain 4 vertical arrows.

• The direction of the arrows continues to alternate strictly starting with an upward arrow: Up, Down, Up, Down (↑, ↓, ↑, ↓).

Comparing with the given options, the figure with 4 alternating arrows starting with an upward arrow and ending with a downward arrow corresponds to Option 4:

Therefore, the figure in Option 4 completes the logical series.
