B．if the quantity in Column B is greater
C．if the two quantity are equal
D．if the relationship cannot be determined from the information given请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：D
解析：△RST位于XY坐标平面中，顶点R和T的坐标(coordinate)分别是(0，0)和(6，0)。△RST的面积为12。解：本题的正确答案是(D)。由△RST的面积为12，RT长度为6，可以推出S点的纵坐标为±4，而横坐标则为直线y=+4和y=-4上的任一点，所以本题为无法判断。
