The distance of Neptune and Saturn from the Sun are respectively. \[\text{1}{{0}^{\text{13}}}\]and \[\text{1}{{0}^{\text{12}}}\] metres and their periodic times are respectively\[{{T}_{n}}\]and\[{{T}_{s}}\]. If their orbits are assumed to be circular, the value of\[{{T}_{n}}/{{T}_{s}}\]is

• A.  100                       
• B.  \[10\sqrt{10}\]    
• C.  \[\frac{1}{10\sqrt{10}}\]                             
• D.  10
