Testing for biological molecules — practice question

A student needed to estimate the concentration of glucose in a solution by carrying out the Benedict’s test. The student was given a $1.0\,\text{mol dm}^{-3}$ glucose solution and instructed to prepare a $0.6\,\text{mol dm}^{-3}$ solution through proportional dilution. Which row gives the correct volumes of the $1.0\,\text{mol dm}^{-3}$ glucose solution and distilled water required to prepare the $0.6\,\text{mol dm}^{-3}$ solution?
