Average distance of the earth from the sun is\[{{L}_{1}}\]. If one year of the earth = D days, one year of another planet whose average distance from the sun is \[{{L}_{2}}\] will be

• A. \[D{{\left( \frac{{{L}_{2}}}{{{L}_{1}}} \right)}^{1/2}}days\]  
• B. \[D{{\left( \frac{{{L}_{2}}}{{{L}_{1}}} \right)}^{3/2}}days\]  
• C. \[D{{\left( \frac{{{L}_{2}}}{{{L}_{1}}} \right)}^{2/3}}days\]  
• D. \[D\left( \frac{{{L}_{2}}}{{{L}_{1}}} \right)days\]
