The question figure shows the 3D view of an object. Identify the correct view, looking in the direction of Arrow :
Show Hint
Draw the front elevation as seen along the arrow: the low slab on the left, the two windowed blocks with a step between them, and the stepped block above.
Looking along the arrow we see the long face of the object, with the left end of the object on the viewer's left. 1. The left half of the elevation is the low base slab, seen as a long low rectangle. 2. To the right of it rise two taller blocks, each with one rectangular window. The left block is at the front and the right block is set back, so a vertical line (the step edge) separates them and runs the full height of the view. 3. Above the two windowed blocks stands a taller block whose front is again made of two parts, a nearer part over the left block and a set-back part over the right block, ending in a further vertical edge; so the upper band shows three sections: a wide one followed by two narrow ones of about equal width. Option (1) has no third section in the upper band, option (2) has no step line and no divisions, and option (3) lacks the full-height step line and has an extra horizontal line. Only option (4) has the full-height step line and the upper band divided into one wide and two narrow parts. Answer: (4) the view with the full-height step line and the upper band divided into one wide and two narrow parts
