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

The correct figure to complete the given series is shown in the fourth option:


Step-by-step Explanation:

To determine the missing figure in place of '?', let us analyze the step-by-step changes in the elements across the given series of images:

1. Inner Arcs Inside the Circle:
- Figure 1: Contains a central circle with 0 inner arcs.
- Figure 2: 2 inner arcs are added inside the circle (one top curved arc and one bottom curved arc).
- Figure 3: The number of inner arcs remains 2.
- Figure 4: 2 more inner arcs are added, making a total of 4 inner arcs inside the circle (two top arcs and two bottom arcs).
- Figure 5 ('?'): Following the alternating pattern, the number of inner arcs should remain 4.

2. Outer Vertical Lines:
- Figure 1: 0 outer vertical lines.
- Figure 2: 0 outer vertical lines.
- Figure 3: 1 vertical line is added on the left side touching/adjacent to the circle.
- Figure 4: The outer vertical lines remain 1 on the left side.
- Figure 5 ('?'): Following the alternating sequence (+2 inner arcs → +1 outer line → +2 inner arcs → +1 outer line), 1 additional vertical line must be added on the right side of the circle, giving a total of 2 vertical lines (one on the left and one on the right).

Combining these observations, the missing figure must contain a circle with 4 inner arcs inside and 2 vertical lines flanking it on either side (left and right).

This matches the figure provided in the fourth option.
