A 10-inch telescope is used to determine if what appears to be one star is actually two stars. Stars are so far away that they are essentially point sources. How close, in angle, can two stars be and still be resolved by this telescope? Use a wavelength of 550 nm.

A) 1.5 × 10-4 degree
B) 4.2 × 10-8 degree
C) 2.64 × 10-6 degree
D) 3.0 × 10-4 degree
E) 6.6 × 10-8 degree
