Why do NH₃ and SCl₂, despite having comparable bond angles, have different molecular geometries?

NH₃ and SCl₂ have different molecular geometries because they have different electron arrangements.

NH₃ and SCl₂ have different molecular geometries because they have different numbers of lone pairs.

NH₃ and SCl₂ have different molecular geometries because they have different numbers of electron groups.

All of the above.
