Assume that light of wavelength $600\text{nm}$ is coming from a star. The limit of resolution of telescope whose objective has a diameter of $2\text{m}$ is:

1. A
   $3.66\times 10^{-7}\text{rad}$
2. B
   $1.83\times 10^{-7}\text{rad}$
3. C
   $7.32\times 10^{-7}\text{rad}$
4. D
   $6.00\times 10^{-7}\text{rad}$
