The angular resolution formula,
Sin A= 0.25 (Wavelength ÷ Diameter)
where, wavelength is taken in micrometer and diameter is in meter.
Here, wavelength (W)= 650 nm = 0.65 μm (converting nanometer into micrometer)
Diameter= 2 m
now, according to the formula,
Thus, the correct answer is option (C) i.e. 0.082 arc second.
