What best describes the bonding in a carbon dioxide molecule?

carbon shares two of its electrons, and each oxygen shares four of its electrons.
carbon shares four of its electrons, and each oxygen shares two of its electrons.
carbon receives two electrons from each of the two oxygen atoms.
carbon transfers two electrons to each of the two oxygen atoms.

Answer;

Carbon shares four of its electrons, and each oxygen shares two of its electrons.

Explanation;Carbon dioxide is formed from combustion reactions, which involves a reaction between carbon and oxygen gas. Carbon dioxide molecule is formed from one carbon atom and two oxygens. As an element, carbon only has 4 outer shell electrons and oxygen 6.The two atoms require to gain electrons to achieve a stable configuration; carbon require to gain four electrons and oxygen requires two electrons.Double covalent bonds form between the atoms, where two electrons from each atom are shared making 4 bonding electrons in total.
