Explain how a graph that shows percentage change can show descending bars (or a descending line) even when the variable of interest is increasing. Choose the correct answer below. O A. The horizontal axis on the graph has an opposite direction. O B. The horizontal axis on the graph represents unequal intervals such that the drop-off means only the actual value of the variable rises by smaller amounts. O C. The vertical axis on the graph has an opposite direction. O D. The vertical axis on the graph represents a percentage change such that the drop-off means only the actual value of the variable rises by smaller amounts
