Answer : The correct option is C.
Explanation :
Covalent bond : Covalent bond forms when two non-metal atom share a pair of electrons.
In the covalent bond formation of carbon dioxide, carbon and oxygen atom share four pair of electrons. The carbon atom joined by four covalent bonds to two oxygen atoms.
The valence electrons in carbon atom = 4
The valence electrons in two oxygen atom = 2(6) = 12
Therefore, these atoms are rearranged to form the bonds by the sharing of many valence electrons between the atoms.
The lewis-dot structure of carbon dioxide is shown below.
