Addition & Removal Pattern — Easy Matrix Reasoning Question

What to learn from this pattern

Family: POSITION SWAP (pair exchange).

Explanation

Family: POSITION SWAP (pair exchange). Rule: two objects (triangle-red, circle-blue) exchange positions between consecutive cells. Even cells (0,2,4,6,8): triangle-red at top-left, circle-blue at bottom-right. Odd cells: positions swapped. Cell 8 — even parity — matches even state — option A.

Why the other options are wrong

• Bmissed-conditional-rule — applies the odd-parity swap to an even-parity cell
• Cmissed-conditional-rule — moves objects to different corners; the swap exchanges position not shape
• Dmissed-conditional-rule — swaps colours between objects instead of swapping positions
