Which of the options fits with the black solid figure and makes it a square?
Show Hint
Treat the black shape as a set of row by row gaps rather than one picture, and treat every option as strips that must fill those gaps exactly. Place each option under the black shape in your mind and check whether the combined right edge becomes one straight line, even a single strip that is too long or too short will leave a visible step in the edge. Do not judge an option by its overall look, check it strip by strip against the row directly above it.
Step 1: Analyzing the figure.
The given black solid figure resembles a partial square, and we need to identify which option, when added, completes the square shape. The correct option will fit seamlessly to form a perfect square. Step 2: Analyzing the options. (A) Option A: This does not fit the given figure correctly to form a square. (B) Option B: This does not complete the figure into a square. (C) Option C: This is correct, as it perfectly fits the given figure to make a square. (D) Option D: This does not form a square when added to the figure. Step 3: Conclusion.
The correct answer is (C) because it correctly completes the given figure into a square.

Concept:
The black shape above the options is one broken half of a square. Every option is the missing other half, made of horizontal strips of different lengths. Only one option has strip lengths that exactly cancel out the gaps in the black shape, so that together the two halves form one solid, evenly edged square.
Step 1: Read the black shape as a set of measurements, not just a picture.
Look at the lower edge of the black shape row by row. Some rows reach far to the right, and some rows stop short, leaving a gap of open white space. Each gap is a place where a strip from the correct option must sit, and the length of that strip must be exactly the size of the gap, no shorter and no longer.
Step 2: Turn each option into a matching test instead of a guess.
For each option, place its strips directly below the black shape, row by row. If a row in the black shape is short, the matching strip below it must be long enough to reach the same total width as every other row combined. If even one strip in an option is too long or too short, that option leaves a jagged, uneven right edge instead of a straight square edge, and it can be crossed out immediately.
Step 3: Apply this row by row check to eliminate three options.
Options A, B and D each have at least one strip that is either too long or too short compared to the gap directly above it, so stacking them under the black shape leaves the right edge uneven, not a straight line. Option C is the only one where every strip length exactly completes the gap above it, so the combined shape has a perfectly straight, even right edge, forming a square.
