(A) The resolution $(d)$ of a light microscope is determined by the formula $d = 0.61 \lambda / NA$,where $\lambda$ is the wavelength of light used and $NA$ is the numerical aperture of the objective lens.To obtain 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 given options,blue light has the shortest wavelength (approximately $450-495 \ nm$) compared to green,yellow,and red light.Therefore,blue light provides the best resolution.

$(b)$ Rough endoplasmic reticulum	$(ii)$ Lipid synthesis
$(c)$ Golgi complex	$(iii)$ Glycosylation
$(d)$ Centriole	$(iv)$ Spindle formation
