Show Hint
Looking at the front face: the low ledge on the left, the tall column in the middle with the open slot at its top and the notch at its bottom, and two steps falling to the right.
Looking along the arrow we see the front elevation. From left to right: the low ledge, the tall middle column, then two steps coming down towards the right. The front of the column has the open rectangular slot at the top and the notch at the bottom; both are open to the front, so they show as full (continuous) lines. Option (1) shows exactly this stepped outline with the two rectangles drawn in continuous lines. Option (2) has a dashed line and a slanting left edge, which cannot occur. Options (3) and (4) are rectangles divided by vertical lines, like a top view, and do not show the stepped outline. Answer: (1) the first view
