In the question figure, the top, front and right side view is given. Identify the most appropriate 3D view of the object from the answer figures.
Show Hint
Combine the three orthographic views: the top view fixes the outline and the cut features (chamfer, step, square notch, quarter circle), and the front and side views give their depths.
The top view is a rectangle with a diagonal line at the top-left (an inclined face), a rectangular step at the top-right, a small square notch on the front edge and a quarter circle at the front-right corner. The front view shows two notches cut down from the top edge: a deeper square one in the left-middle and a shallower one over the right third. These are the square notch and the quarter-circle pocket seen from the front. The right side view shows a stepped top edge with a full-height strip in the middle, which confirms the stepped top with a pocket at the front-right. The arc is a quarter circle centred on the corner and the front view shows it as a straight rectangular notch, so the feature is a concave quarter-cylindrical pocket cut into the corner, not a raised dome. Option 1 shows exactly this: a rectangular block with the inclined face at the back-left, the step at the back-right, the square notch in front and a concave quarter-round pocket at the front-right corner. Option 2 shows the quarter circle as a raised convex cone (wrong), option 3 has a rounded outer top edge that contradicts the rectangular outline of the top view, and option 4 has a window-like hole in place of the inclined face and the notch. Answer: (1) Option 1 figure
