Visual IQ puzzle (MENSA Sweden, difficulty 1)
Correct answer: B
Explanation: Each figure is made of a rhombus with an arrow inside, that can be either black or white. Consider the rows and the columns: when moving from left to right in a row or from top to bottom in a column, the figure gets rotated by 90 degrees clock-wise. Each row and column must have two figures with a black arrow and one figure with a white arrow.
