To solve this question, we need to identify the pattern or relationship between the given figures. Let's analyze the sequence:

1. First Pair Analysis: The first pair consists of a pentagon inside a triangle and then a triangle inside a pentagon.
   • The pattern involves switching the shapes and positioning them inside each other.
2. Second Pair Hypothesis: Applying the same logic, the second pair starts with a circle inside a hexagon.
   • Following the pattern, the next figure should be a hexagon inside a circle.

Now let's look at the options:

The third image from the options matches our expected figure, which is a hexagon inside a circle. Therefore, it is the correct choice.

Conclusion: The answer is the figure that has a hexagon inside a circle, represented by the third image option.
