In each of the following questions, find out which of the answer figures (1),…

Concept: In a figure-matrix completion item, each row is built from four independent visual attributes — head shape, body shape, arm position, and leg style — and every row uses exactly three different forms of each attribute, one per cell, with no attribute value repeated within the row. The missing figure is found by checking, attribute by attribute, which of the three forms has not yet appeared in that row.

Applying it to the third row:

1. Heads across the matrix take three forms — triangle, circle, square. The third row already shows a circle head and a triangle head, so the missing figure needs a square head.

2. Bodies across the matrix take three forms — rectangle, plain stick, and teardrop. The third row already shows a rectangle body and a teardrop body, so the missing figure needs a plain stick body.

3. Arms across the matrix take three positions — angled up from the shoulder, held level, and angled down from the shoulder. The third row already shows arms angled up and arms held level, so the missing figure needs arms angled down.

4. Legs across the matrix take three styles — open and apart with hook-shaped feet, crossed with solid dot feet, and crossed with open ring-shaped feet. The third row already shows the open/hook style and the crossed/dot style, so the missing figure needs crossed legs ending in open ring-shaped feet.

Putting it together: the missing figure has a square head, a plain stick body, arms angled down from the shoulder, and crossed legs ending in open ring-shaped feet.

Cross-check: the same one-of-each rule already holds without exception in the first two rows, confirming it as the rule governing this matrix. Checking the four answer figures against all four required attributes together, only one figure matches every attribute at once — the other three each repeat an attribute value already used earlier in the third row.
