(B) The resolving power $(R.P.)$ of a telescope is defined as the inverse of the minimum angular separation between two distant objects that can just be distinguished by the telescope.Mathematically,the resolving power is given by the relation $R.P. = \frac{D}{1.22 \lambda}$,where $D$ is the diameter (aperture) of the objective lens and $\lambda$ is the wavelength of light used.Since $R.P. \propto D$,increasing the aperture $D$ of the objective lens directly increases the resolving power of the telescope,allowing it to distinguish finer details of distant objects.
