编写数学动画，现在以附件的形式给你一道数学题，请你给出详细的解答过程，因为你面对的是小学生群体，所以你要尽可能的详细，动画要简洁生动。---**Textual Information:** **Question Stem:** 从所给的四个选项中，选择最合适的一个填入问号处，使之呈现一定的规律性 ( ) **Options:** A B C D **Chart/Diagram Description:** **Type:** A sequence of diagrams illustrating a pattern, followed by multiple choice options. **Main Elements:** The image contains two rows of boxes, each box containing a geometric figure. The top row shows a sequence of 5 figures and a question mark in the 6th box. The bottom row shows 4 figures, labeled A, B, C, and D, as options to fill the question mark. **Top Row Sequence:** 1. **Box 1:** A circle with a vertical line segment inside it extending upwards from the bottom, and a horizontal line segment extending leftwards from the vertical line. There is a short line segment connected to the bottom of the vertical line extending leftwards. 2. **Box 2:** A circle with a vertical line segment inside it extending upwards from the bottom, and a horizontal line segment extending rightwards from the vertical line. There is a short line segment connected to the bottom of the vertical line extending rightwards. 3. **Box 3:** A square frame (or rectangle) with a small circle inside its top left corner. A vertical line segment extends downwards from the top left corner of the square frame inside the frame. A horizontal line segment extends rightwards from the bottom of this vertical line segment inside the frame. There is a small square at the bottom right corner of the vertical line. 4. **Box 4:** A square frame (or rectangle) with a circle inside its top right corner. A vertical line segment extends downwards from the top right corner of the square frame inside the frame. A horizontal line segment extends leftwards from the bottom of this vertical line segment inside the frame. There is a small square at the bottom left corner of the vertical line. 5. **Box 5:** A triangle with a vertical line segment extending downwards from the top vertex, and a horizontal line segment extending rightwards from the bottom end of the vertical line to the right side of the triangle. There is a line segment extending from the bottom end of the vertical line to the left side of the triangle. This forms a shape resembling a stylized 'A' inside the triangle. 6. **Box 6:** Contains a question mark "?". **Bottom Row Options:** 1. **Option A:** A circle. Inside the circle, two diagonal lines intersect. 2. **Option B:** A shape resembling the letter 'Z' with horizontal lines at the top and bottom and a diagonal line connecting them. 3. **Option C:** A circle. Inside the circle, a vertical line segment extends downwards from the top. A horizontal line segment extends leftwards from the bottom of the vertical line. A diagonal line extends upwards and rightwards from the intersection of the vertical and horizontal lines. There is a small circle at the intersection of the vertical and horizontal lines. 4. **Option D:** A circle. Inside the circle, two diagonal lines intersect, similar to option A, but with additional short horizontal and vertical line segments intersecting near the center.
