Which statement about the thiocyanate ion, SCN¯ is true?

Which statement about the thiocyanate ion, SCN¯ is true?
(A)its Lewis structure contains an unpaired electron
(B)its shape is bent like that of H2O
(C)only one correct resonance structure can be drawn
(D)there are more than two bonds in the ion
(E)none of these

I thought the correct answer is (D), because of the three resonance structures that could be drawn, all of which contain 4 bonds: 2 σ and 2π
Am I correct?

Thanks for any help
