I’d add “both”, “fluid” or “variable”, and “other” for a better shot at completeness, mostly because there are people whose non-binary gender is an important enough part of their identity that “n/a” seems likely to feel dismissive to them.
Better go with the text field then if there’s really demand for all those. The base three would pretty much solve the actually manifesting problem of people not knowing which pronoun to use of other people though.
Are there important options beyond beyond male, female and an explicit n/a for the variable, not applicable, not your business etc cases?
