Solution
The correct option is C resonance In chemistry, resonance is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure. A molecule or ion with such delocalized electrons is represented by several contributing structures.
Each contributing structure can be represented by a Lewis structure, with only an integer number of covalent between each pair of atoms within the structure.Several Lewis structures are used collectively to describe the actual molecular structure, which is an approximate intermediate between the canonical forms called a resonance hybrid.Contributing structures differ only in the position of electrons, not in the position of nuclei.
