Carbon is in group 4 of elements so it can make 4 covalent bonds to be stable and every oxygen atom can have 2 covalent bonds as it is a group 6 element which lacks 2 electrons to achieve stability with 8 electrons in the valence electron shell, so the total no of bonds = no. of Oxygen atoms x 2 = 6 x 2 = 12.

Question asks for total number of electrons, so the number of bonds have to be multiplied by 2 since 1 bond has 2 electrons.
