Select a suitable figure from the given alternatives that would complete the…

Concept:

In this kind of figure matrix, the middle figure in a row equals the left figure with some new lines or curves added on top of it, and the right figure of that same row shows only those newly added lines or curves by themselves, with the original base figure removed.

Application:

1. Row 1: the left cell is a plain triangle. The middle cell is the same triangle with one vertical line down its centre and a small circle at its lower-right corner added. The right cell shows only that added vertical line and circle, with the triangle itself removed.

2. Row 2: the left cell is a square containing a single diagonal from the top-left corner to the bottom-right corner. The middle cell is the same square and diagonal with a horizontal line and a vertical line added through the centre, forming a cross. The right cell shows only that added cross, with the square and diagonal removed.

3. Row 3: the left cell is a square with one curved line joining its top two corners and dipping toward the centre. The middle cell keeps that curve and adds both diagonals, forming an X, together with a second curved line joining the bottom two corners and arching up toward the centre.

4. Following the same rule, the missing right cell of Row 3 must show only the elements that were added between the left and middle cells of that row: the X formed by both diagonals, together with the single curve joining the bottom two corners, with no square, no top curve, and no cross.

Cross-check:

• A figure with only the X formed by the two diagonals, and no curve at all, is missing the curve that Row 3 adds.

• A figure with only a horizontal-and-vertical cross, and no diagonals, repeats the pattern that belongs to the right cell of Row 2, not Row 3.

• A figure with the X together with a curve along the upper edge repeats the left cell's own curve instead of the curve that gets newly added.

• A figure with the X together with a curve along the lower edge matches exactly the elements that are added between the left and middle cells of Row 3.

So the figure that completes the matrix is the one showing the X formed by both diagonals together with a single curve along the lower edge.
