The problem figure shows the top view of objects. Looking in the direction of the arrow, identify the correct elevation, from amongst the answer figures.
Show Hint
Count the vertical edges each object shows from the arrow side: a tilted L-shaped block shows three internal edges, a tilted bar shows one.
The plan has three objects: a tilted L-shaped block at the top left, a rectangular block with a smaller rectangular block attached on its near side at the top right, and one tilted bar in front at the bottom. Seen from the arrow side: the tilted L-shaped block shows its outer left and right edges and three internal vertical edges (its nearest corner, its inner corner and the step), so it appears as a box with three internal lines spread across its width. The tilted bar shows two faces separated by one vertical edge near its middle. The rectangular block appears as a tall plain rectangle, and the smaller block attached in front of it appears as a narrower, lower rectangle inside it. Option (1) shows the tilted bar as a plain box without its dividing edge. Option (2) shows only two lines on the L-shaped block. Option (3) crowds the lines of the L-shaped block at the left, which does not match the plan. Option (4) shows all of these features correctly: three internal lines on the L-block, one line on the bar, and the narrower rectangle inside the large rectangle. Answer: (4) elevation (4)
