Step 1: Understand the problem and identify the concept being tested.
We are asked to determine the molecular geometry of carbon dioxide (CO₂) based on its Lewis structure. The concept being tested here is an understanding of molecular geometry and its relationship with Lewis structures.
Step 2: Draw the Lewis structure of CO₂.
Carbon dioxide consists of one carbon atom and two oxygen atoms. The carbon atom forms double bonds with both oxygen atoms. The Lewis structure for CO₂ is: \mathrm{O}=\overset{\cdot \cdot}{\mathrm{C}}=\overset{\cdot \cdot}{\mathrm{O}}
Final Answer
The molecular geometry of CO₂ is linear (option B).
