Frequency Count Pattern — Hard Matrix Reasoning Question

Explanation

**Rule:** Each column must have all three fill types (solid, stripe, empty) — no repeats. - Look at column 3: two fills are already there. - Find the missing fill value. - Option D completes the set with the third fill type. - Options A and C repeat fills already in the column. - Options B and E use shapes not in the grid.

Why the other options are wrong

• BPicked a shape the grid doesn't use, with a fill already in the line — it can't complete the pattern.
• CPicked a value that already appears in this column — it can't complete the set.
• EPicked a shape the grid doesn't use, with a fill already in the line — it can't complete the pattern.
