There are three blocks, A, B and C. Block A has a medium yellow triangle. Then, we have block B with one big yellow circle and a small yellow square in it. The big yellow circle is touching the bottom edge of this block. It is near to and to the right of the small yellow square. Finally, to the right of block A we have block C which is below block B.
