If mt is modulation index of FM. What is the value of ratio $$\frac{{{{\left( {\frac{{\text{S}}}{{\text{N}}}} \right)}_{{\text{WBFM}}}}}}{{{{\left( {\frac{{\text{S}}}{{\text{N}}}} \right)}_{{\text{AM}}}}}}$$ for 100% amplitude modulation with identical total transmitted power?
A. $$\frac{9}{2}{\text{m}}_{\text{f}}^2$$
B. $$\frac{3}{2}{\text{m}}_{\text{f}}^2$$
C. $$\frac{3}{2}{\text{m}}_{\text{f}}^3$$
D. $$\frac{9}{2}{\text{m}}_{\text{f}}^3$$
