Correct Answer: D
Explanation:
Answer figure (a) is the correct option. So, the answer is Option D.
See the third row. The first box has 2 circles & 0 triangles, 2nd has 1 circle (decrease by 1) & 1 triangle (increase by 1). So 3rd box must have 0 circles ad 2 triangles.
Same pattern is followed in all rows. You solve this by taking columns instead of rows too.
