(C) Given that,maximum amplitude,$A_{\max} = 10 \,V$. Minimum amplitude,$A_{\min} = 4 \,V$. The modulation index $\mu$ is defined as the ratio of the difference of maximum and minimum amplitudes to the sum of maximum and minimum amplitudes. $\mu = \frac{A_{\max} - A_{\min}}{A_{\max} + A_{\min}}$. Substituting the given values: $\mu = \frac{10 - 4}{10 + 4} = \frac{6}{14} = \frac{3}{7}$.
