The same stepped object is now seen from the right side, in the direction of the arrow at the lower right. The base slab is the widest part and forms the full-width bottom band. Where its slanted front face meets the right-hand face there is a vertical edge at about half the width, so the slab band must show one vertical line near the middle. The middle block and the small top block sit towards the right end, so the elevation looks like a staircase rising to the right: a full-width bottom band, a middle band over the right half and a narrow top band over the right quarter. The edges of the stacked blocks line up: the vertical line at half width runs up through the middle band (the left edge of the middle block and the slab edge fall on one line), and the left edge of the top block continues down through the middle band. Option 2 has a thick line at about three-quarters width running through all three bands including the slab, which has no edge there. Option 3 puts the slab edge at about two-thirds width and shows no continuing edges. Option 4 has no edge continuing below the top block. Option 1 shows the correct staircase with the continuing edges, so it is the most appropriate elevation. Answer: (1) Option 1
