1The 3x3 grid below follows two independent rules: every cell in a given row uses the same shape, and every cell in a given column uses the same size. Study the pattern across the completed rows and columns, then choose the option that correctly completes the missing bottom-right cell.

Rule: each row is assigned a fixed shape (hexagon for row 1, pentagon for row 2, diamond for row 3) that stays constant across all three columns, and each column is assigned a fixed size (small for column 1, medium for column 2, large for column 3) that stays constant across all three rows. The missing cell is row 3, column 3, so it must combine row 3's shape (diamond) with column 3's size (large) — this is option A. Option D uses the correct row-3 shape (diamond) but the wrong column size (medium instead of large), violating the column rule. Option B uses the correct column-3 size (large) but the wrong shape (pentagon instead of diamond), violating the row rule. Option C uses the correct size but substitutes a parallelogram, a shape that does not appear anywhere in the grid, violating the row rule entirely.
