$**Question 23:** What is the point group of the Audi logo? A. $ C_4 $ B. $ C_2 $ C. $ D_{2h} $ D. $ C_{2h} $ E. $ S_4 $ **Image Description:** The image shows the Audi logo, which consists of four interlocking rings. These rings are aligned horizontally in a linear sequence, representing a symmetrical design. **Explanation on Educational Website:** The Audi logo is a well-known symbol made up of four interconnected rings. Each ring represents one of the four founding companies of the Auto Union. Understanding the point group of such a logo involves analyzing its symmetry elements, such as rotational axes and mirror planes. In the context of point groups, it is essential to understand that these groups describe the symmetry of a geometric object. Each choice in the multiple-choice question refers to a specific type of symmetry: - $ C_4 $: Cyclic group with a fourfold axis of rotation. - $ C_2 $: Cyclic group with a twofold axis. - $ D_{2h} $: Dihedral group with horizontal mirror planes. - $ C_{2h} $: Cyclic group with a twofold axis and a horizontal mirror plane. - $ S_4 $: Improper rotation group with a fourfold axis. The educational value here lies in recognizing the symmetry properties of logos, which involve complex group theory concepts in chemistry, physics, and mathematics.$
