Answer

Structure A has the lowest formal charges.

Work Step by Step

Structure A has a formal charge of 0 on all atoms, as shown in the calculations below: F.C. = (# of Valence e-) - (Number of Bonds) - (Number of e- in lone pairs) For C: F.C. = 4 - 4 - 0 = 0 For O: F.C. = 6 - 2 - 4 = 0 For Cl: F.C. = 7 - 1 - 6 = 0
