If D1 and D2 are depths of water upstream and downstream of a hydraulic jump, the loss of head at the jump, is
A. $$\frac{{{{\left( {{{\text{D}}_2} - {{\text{D}}_1}} \right)}^3}}}{{{{\text{D}}_1}{{\text{D}}_2}}}$$
B. $$\frac{{{{\left( {{{\text{D}}_2} - {{\text{D}}_1}} \right)}^3}}}{{2{{\text{D}}_1}{{\text{D}}_2}}}$$
C. $$\frac{{{{\left( {{{\text{D}}_2} - {{\text{D}}_1}} \right)}^3}}}{{3{{\text{D}}_1}{{\text{D}}_2}}}$$
D. $$\frac{{{{\left( {{{\text{D}}_2} - {{\text{D}}_1}} \right)}^3}}}{{4{{\text{D}}_1}{{\text{D}}_2}}}$$
