In graph A, the rate of reaction goes down steadily as the substrate concentration goes up. In graph B, the rate of reaction increases and then plateaus as the substrate concentration increases. In graph C, the rate of reaction increases and then drastically decreases as the concentration of substrate increases. In graph D, the rate of reaction steadily increases as the substrate concentration increases.

Which of the graphs above correctly shows the relationship between substrate concentration and rate of reaction?
