(a)
Interpretation:
The Fischer projections of
Concept introduction:
The Fischer projection is drawn by taking chiral carbons into consideration. The chiral carbons of the molecule are represented by the intersection of two lines in Fischer projection. The groups attached to the chiral carbon are attached to that intersection point. The D or L form is decided on the basis of the attachment of the hydroxyl group on the chiral carbon which is farthest from the carbonyl carbon. When the hydroxyl group is on right side, then it is D form. When the hydroxyl group is on left side, then it is L form.
