Correct answer: D
Concept: In a rotation/reflection-based classification series, every figure is built from the same base shape; identify the one relationship that stays fixed when the base shape is rotated or mirrored, then check whether that relationship still holds in each figure. The figure that breaks the fixed relationship is the one that differs from the rest.
Application: Each figure here has two near-vertical strokes, and each stroke ends in one small right-angle hook. Tracing the hook directions across the five figures:
Figure 1 - the lower stroke's hook bends to the right and the upper stroke's hook bends to the left - opposite directions.
Figure 2 - the lower stroke's hook bends to the left and the upper stroke's hook bends to the right - opposite directions.
Figure 3 - the upper stroke's hook bends to the left and the lower stroke's hook bends to the right - opposite directions.
Figure 4 - the lower stroke's hook bends to the left and the upper stroke's hook ALSO bends to the left - the same direction, not opposite.
Figure 5 - the upper stroke's hook bends to the right and the lower stroke's hook bends to the left - opposite directions.
Cross-check: Rotating or mirroring the base figure only changes which stroke sits on top and which side each hook faces; a 180-degree rotation still keeps the two hooks pointing away from each other, and a mirror reflection flips both hooks together - so an opposite-direction pair can never turn into a same-direction pair. Figures 1, 2, 3, and 5 are exactly this base figure rotated or mirrored (their two hooks stay opposite); Figure 4 cannot be produced from the same base figure by any rotation or reflection, because both of its hooks point the same way.
Result: Figure 4 is the one that is different from the rest.
