Emil Fischer arbitrarily established the D/L Relative Configuration system. Which specific molecule was chosen as the universal standard reference, and how is the 'D' configuration defined?

Question

Correct answer: C. The D/L relative configuration system is deeply anchored to the arbitrary historical standard of (+)-Glyceraldehyde (2,3-dihydroxypropanal). In its standard vertical Fischer projection, if the defining hydroxyl () group on the chiral center is oriented on the right side, the molecule is assigned the 'D' configuration. If on the left, it is 'L'.
