Concept:
The required view is the orthographic projection in the direction of the arrow.
Only features directly visible from the arrow direction should appear.
Hidden edges and features not facing the observer are not shown.
Step-by-step analysis:
The arrow indicates viewing the object from the front side of the fork-shaped opening.
From this direction, the following features are visible:
The semi-circular cut-out at the bottom (open towards the observer),
The circular hole in the upper block, visible as a circle,
A simple rectangular outer boundary.
The horizontal step seen in the 3D view is along the depth and hence does not appear as a dividing line in this projection.
Comparison with options:
Option (A): Shows extra internal divisions not visible from this direction.
Option (B): Does not show the curved cut-out correctly.
Option (C): Shows an incorrect horizontal separation.
Option (D): Correctly shows:
The circular hole,
The semi-circular bottom cut-out,
No unnecessary internal lines.
Hence, the correct view when looking in the direction of the arrow is Option (D).
