(C) The resolution $(d)$ of a light microscope is determined by the formula $d = \frac{0.61 \lambda}{NA}$,where $\lambda$ is the wavelength of light used and $NA$ is the numerical aperture of the objective lens.To achieve the best resolution,the value of $d$ must be as small as possible.Since $d$ is directly proportional to the wavelength $(\lambda)$,using light with the shortest wavelength will result in the smallest $d$,thereby providing the highest resolution.Among the visible spectrum colors,blue light has the shortest wavelength (approximately $450-495 \ nm$) compared to yellow,green,or red light.Therefore,blue light provides the best resolution for a light microscope.
