Possibly, I thought the electron domain of the particular molecule was bent but that isn't one of the answers given
You are confusing them. The electron domain geometry is trigonal planar, with a lone pair occupying one of the trigonal positions, and N-O bonds the other two. The molecular structure (arrangement of the atoms) is bent. Similarly, H
2O has a bent molecular structure, but a tetrahedral electron domain geometry at the oxygen (two bonds and two lone pairs).
You can't have a bent electron domain geometry. (What occupies the reflex angle?)
