(D) The resolving power of a telescope is defined as the ability to distinguish between two closely spaced objects. Mathematically,the resolving power is given by the formula $RP = \frac{D}{1.22 \lambda}$,where $D$ is the diameter (aperture) of the objective lens and $\lambda$ is the wavelength of light used. From this relation,it is clear that the resolving power is directly proportional to the aperture $D$ of the objective lens. Therefore,to achieve a large resolving power,the aperture of the objective lens should be as large as possible.
