Solution

The correct option is A I
The structure A represents Fischer Projection of a compound. The structures I to IV represents Wedge-Dash Notations for the same compound. The Wedge-Dash Notation I is the correct representation of structure A.

Note:

In a Fischer Projection, the vertical lines are oriented away from you and the horizontal lines are oriented toward you.

In Wedge-Dash Notation for three-Dimensional Representation of an organic molecule, the dashed bond represents a bond below the plane of the paper. The wedged bond represents a bond above the plane of the paper. The remaining two bonds (represented by the solid line) are in the plane of the paper.

Hence, the correct option is $A$
