A. (2D, 3D, 4L, 5D)-2, 3, 4, 5, 6-pentahydroxyhexanal
B. D-2, 3, 4, 5, 6-pentahydroxyhexanal
C. 6-oxo-(2D, 3L, 4D, 5D)-2, 3, 4, 5, 6-pentahydroxohexane
D. (2D, 3L, 4D, 5D)-2, 3, 4, 5, 6-pentahydroxyhexanal
Correct Answer – D
When -OH is present at right side of horizontal line & high priority at the top than it is consider as D & if left side then L.
