Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Given molecule has three chiral centres, so its Fischer projection must preserve the relative configuration at all three centres.

In converting wedge–dash to Fischer, keep the carbon chain vertical with the terminal CH₃ groups at top and bottom.

After orienting the molecule appropriately, the OH groups are arranged as right, left, left from top to bottom.

Thus the Fischer projection has: CH₃–(H/OH)–(OH/H)–(OH/H)–CH₃.

This arrangement matches Option (D).
