To solve this problem, we need to identify the pattern in the given series of figures and determine which figure can logically be placed in the position of the question mark. Let's analyze the pattern step-by-step:

1. The figures show a large square divided into four smaller triangles.
2. Each smaller triangle has a small square inside it. The position of the small squares rotates in a consistent pattern.
3. Observe the movement of the small squares in each figure as you progress from left to right:
   • In the first figure, the small squares are positioned in the top-left and bottom-right triangles.
   • In the second figure, they move to the top-right and bottom-left triangles.
   • In the third figure, they return to the top-left and bottom-right triangles.
   • In the fourth figure, they again shift to the top-right and bottom-left triangles.
4. This pattern indicates an alternating sequence of the positions of the small squares.
5. Following this pattern, the next figure should have the small squares in the top-left and bottom-right triangles.

Thus, the correct figure following this pattern is:

This option maintains the observed pattern of alternating positions for the small squares. Therefore, it is the correct answer.
