Question

The question figure shows the 3D view of an object. Identify the correct top view of the object.

• A. Option 1
• B. Option 2
• C. Option 3
• D. Option 4

Hint:

In top-view problems, ignore all height variations and focus only on what is directly visible from above.

Answer 1

The Correct Option is D

Concept:
A top view shows only those features visible from directly above.
Vertical features like holes appear as circles in the top view.
Curved cut-outs that are open on the front but not on the top do \emph{not} appear as curved shapes in the top view. Step-by-step analysis:
The object has a rectangular top surface.
There is a cylindrical hole drilled vertically through the upper block, which must appear as a circle in the top view.
The front portion has a curved opening, but since it is not open from the top, it does not affect the top view outline.
The stepped nature of the object creates a horizontal division in the top view. Comparison with options:
Option (A): Shows the circle but places the curved cut-out incorrectly.
Option (B): Missing the circular hole.
Option (C): Also missing the circular hole.
Option (D): Correctly shows:
Rectangular outline,
Horizontal division due to the step,
Circular hole at the correct position. Hence, the correct top view of the given 3D object is Option (D).
