Examine the three graphs (a), (b), and (c) depicting the effect of various factors on enzyme activity. Which of the following correctly describes curve (c)?

1. The velocity of reaction continuously increases indefinitely in a linear manner with increasing substrate concentration.
2. Graph (c) demonstrates that the enzyme is denatured at higher substrate concentrations.
3. Graph (c) shows that at \( K_m \), the reaction velocity is maximum (\( V_{\max} \)).
4. Velocity increases initially with substrate concentration and reaches \( V_{\max} \), beyond which further increase in substrate does not increase velocity because enzyme molecules are saturated.
