解答这个问题---**Textual Information:** **Question Stem:** 3. Which point is the reflection of point J over the y-axis? **Options:** A. Point S B. Point T C. Point K D. Point Q **Chart/Diagram Description:** **Type:** Coordinate plane (Cartesian coordinate system) with plotted points. **Main Elements:** * Two perpendicular axes, the horizontal X-axis and the vertical Y-axis, intersect at the origin labeled 'O' (and also corresponding to point Q in the options). * The X-axis is labeled with integers from -5 to 5. * The Y-axis is labeled with integers from -5 to 5. * A grid of lines corresponding to integer coordinates is present. * Five points are plotted and labeled: * Point J: Located at coordinates (3, 1), colored yellow. * Point K: Located at coordinates (-3, 1), colored green. * Point S: Located at coordinates (-3, -1), colored red. * Point T: Located at coordinates (3, -1), colored blue. * Point O (labeled as O, corresponds to option Q): Located at coordinates (0, 0), colored purple.
