Quizplus · Accepted Answer

There are 9 σ-bonds in the molecule, which include the single bonds between the atoms and the C-S and C-N double bonds.

There are 5 π-bonds, which consist of the two π-bonds in the C=N double bond, the two π-bonds in the C=S double bond, and one π-bond in the N=C=S triple bond. Therefore, the correct choice is A.
