To determine which lines are perpendicular, we need to know the slopes of each line. Two lines are perpendicular if the product of their slopes is -1, which means that if the slope of one line is \(m\), the slope of the other line must be \(-\frac{1}{m}\).
Without the specific slopes provided for lines A, B, C, and D, I can’t directly determine the relationships. However, if you have the slopes for each line, please provide them, and I can help you identify which lines are perpendicular based on that information.
