帮我讲一下这道题---Question 7 (3分) **Question Stem:** 如图,数轴上点A对应的数是0,点B对应的数是1, BC⊥AB,垂足为B,且BC=2,以A为圆心, AC为半径画弧,交数轴于点D,则点D横坐标的取值范围是( ) **Figure Description:** Type: Geometric figure on a number line. Main Elements: - Number line: A horizontal line segment with an arrow pointing to the right, representing the positive direction. - Points: - Point A is on the number line, labeled with the number 0. - Point B is on the number line, labeled with the number 1. - Point C is located off the number line. - Point D is on the number line, to the right of A, where an arc intersects. - Lines/Segments: - A line segment AB is part of the number line. - A line segment BC is perpendicular to the number line at point B. - A line segment AC is implied as the radius of the arc. - Angle: There is a right angle at B (∠ABC = 90°). - Arc: A circular arc is drawn with center A and radius equal to the length of AC. This arc intersects the number line at point D. **Options:** A. 3到4之间 B. 2到3之间 C. 1到2之间 D. 0到1之间
