Three molecular structures labeled A, B, and C. A. Two groups of circles. The first group is composed of a white and a red circle. To the right is a black circle in the middle with three small white and one large blue circles attached on it. B. Two groups of circles. The first group is composed of a red circle with a small white circle attached on it, attached to a black circle with three small white circles attached on it. To the right is a big blue circle. C. A group of circles. A small white circle is attached on a red circle. The red circle is attached to a black circle. Three small white circles are attached on the black circle. A big blue circle is attached on the black circle.
