Step 1:
The Lewis electron-dot structure for CO^2 should follow the octet rule, where each atom (C and O) is surrounded by 8 electrons. Since carbon is in the middle, it will share electrons with both oxygen atoms through double bonds.
Step 2:
Start by drawing the carbon atom with 4 points around it representing the 4 valence electrons. \begin{array}{cccc} \cdot & \cdot & \cdot & \cdot \ \text{C} & & & \end{array}
Final Answer
The correct Lewis electron-dot diagram for CO^2 is option C: :O=C-O:.
