If V1 is the jet velocity and V0 is the vehicle velocity, then the propulsive efficiency of a rocket is given by
A. $$\frac{{2\left( {\frac{{{{\text{V}}_0}}}{{{{\text{V}}_1}}}} \right)}}{{1 + {{\left( {\frac{{{{\text{V}}_0}}}{{{{\text{V}}_1}}}} \right)}^2}}}$$
B. $$\frac{{\frac{{{{\text{V}}_0}}}{{{{\text{V}}_1}}}}}{{1 + {{\left( {\frac{{{{\text{V}}_0}}}{{{{\text{V}}_1}}}} \right)}^2}}}$$
C. $$\frac{{{{\text{V}}_0}}}{{{{\text{V}}_0} + {{\text{V}}_1}}}$$
D. $$\frac{{{{\text{V}}_1}}}{{{{\text{V}}_0} + {{\text{V}}_1}}}$$
