Explanation:

- Bond-line formula: This representation uses lines to denote chemical bonds, and the ends or vertices of lines represent carbon atoms. It provides a simplified depiction but lacks three-dimensional details.

- Lewis structure formula: It shows atoms, bonding electrons as pairs of dots or lines, and lone pairs. This method is more basic and flat, illustrating molecular connections without 3D orientation.

- Dash-wedge formula: Utilizes dashes and wedges to represent bonds in 3D on a 2D plane. Dashes indicate bonds going away from the viewer, while wedges indicate bonds coming towards the viewer.

- Correct Answer

- Condensed structural formula: This method abbreviates the Lewis structure by compacting groups, showing them linearly without a 3D perspective.
