Short version - BAD QUESTION. I agree that (B) and (C) are unreasonable, and (A) and (D) may be true... or not... and we lack the information to decide.Agree with @Unovan this is a weirdly worded set of answers.
UV-Vis Spectroscopy relies on photons that are more energetic than infrared, so these photons are not absorbed in rotation, translation or stretching of bonds. These photons are absorbed in electron energy transitions.
(A) is sort-of correct because UV spectroscopy is sensitive to the energy levels of bonding electrons.
(B) is incorrect because it has got nothing to do with molecular mass
(C) is incorrect because if we assume the three samples contain the same solute, they have quite different absorbance so their concentrations are not the same
(D) is probably incorrect. The visible spectrum extends from 300 nm to 700 nm and we have no data in that part of the e-m spectrum. If we assume these samples don't absorb in that part, so they are probably colourless, but we can't tell for sure.
This is why many transition metal complexes are coloured - think FeSCN2+ or why colourimetry works. TM complexes aren't abosrbing in the UV-Vis range because of conjugation of multiple bonds.Wait i don't this 'accessible d orbital transitions in transition metal complexes.' like I haven't ever seen it
