Logical Relation Pattern — Extremely Hard Matrix Reasoning Question

Explanation

Correct answer: F • Look down each column. The third cell is the first cell with the shared dots removed. • A dot stays only if it is in the first cell and NOT in the second cell. • So take the first cell's dots, then delete any that also appear in the second cell. • The wrong options combine the cells the wrong way — union, intersection, or XOR — or just copy one cell.

Why the other options are wrong

• AApplied union (∪) instead of difference (−).
• BApplied intersection (∩) instead of difference (−).
• CApplied symmetric difference (XOR) instead of difference (−).
• DCopied the first cell instead of combining the two.
• ECopied the second cell instead of combining the two.
