Two stars are 10 light years away from the earth. They are seen through a telescope of objective diameter 30 cm. The wavelength of light is 600nm. To see the stars just resolved by the telescope, the minimum distance between them should be (1 light year `= 9.46 × 10^15m`) of the order of :
A. `10^(8)` km
B. `10^(6)` km
C. `10^(10)` km
D. `10^(11)` km
