To draw the Lewis structure of the polyatomic ion, you would have to add one electron to those in the structures of Cl, O, O and O.

Option A

Explanation:

It is a kind of representation of electrons present in valence shell of each element.  For easy understanding of how the outermost electrons will be arranged for bonding purpose, Lewis structure is used.

As we know that carbon has an outermost electron number of 4. So 4 electrons are required as the electrons in the outermost shell of each carbon. But here only three electrons are there, so one electron need to be added in the Lewis structure of .
