Concept:
- In an embedded-figure question, the exact shape of figure (X) is hidden, line for line, inside a more elaborate figure in one of the options, with no extra or missing lines at the points where it should close.
- Ignore the additional lines drawn around it in each option, and trace only the lines that reproduce X's exact shape and proportions.
Step 1: Study the shape of figure (X).
(X) is an upright shape: a vertical stem running down the centre from a horizontal bar at the top, and spreading outward symmetrically at the bottom, similar to a capital "I".
Step 2: Search each option for this exact combination of lines.
Look for a straight vertical centre line meeting a horizontal top edge, with the lower portion opening outward symmetrically on both sides, exactly as in (X).
Step 3: Eliminate the options that do not reproduce this shape.
In three of the four options, the internal lines form a different structure altogether, such as a rectangle divided into unrelated panels, an arched top, or extra internal partitions that do not match X's proportions.
Step 4: Confirm the matching option.
One option contains a vertical centre line from the top edge down to a point where it opens into two symmetric slanted lines reaching the bottom corners, matching (X)'s stem-and-spread shape exactly, with no unmatched extra lines needed.
Final Answer: Option 4
