Solution

Number of Covalent Bonds
a) Structures with more covalent bonds are more stable.
b) Structures where all atoms have complete valence octets provide greater stability.
Charge Separation
a) Neutral molecular structures are inherently more stable than charged ones.
b) Minimizing the distance and amount of charge separation decreases the potential energy.
Electronegativity Alignment
a) Negative formal charges belong on highly electronegative atoms like oxygen or nitrogen.
b) Positive formal charges belong on electropositive atoms like carbon.
Charge Proximity
a) Like formal charges should be kept as far apart as possible to prevent repulsion.
b) Opposite formal charges should be placed close together to maximize stabilization.

Following the above rules, B has the most stable resonating structure.
Correct option: (B)
