The purpose of these questions is to verify your identity; they have your DoB, and are asking the question to confirm that you are who you say you are, so if you answer N/A when the correct answer is one of the other 4, you’ll be denied access to whatever you’re signing up for.
All that said, “What month were you born in?” would have been a much better question for the reasons OP notes.

We were discussing this in the atheism community and the advantage of zodiac sign over birth month is that there is not an even overlap between months and zodiac signs, so 30% of people will be born in a different month than the one associated with the sign. I’m one of these. I was born near the end of the month so the sign I would be associated with is not the sign people associate with the month.
Don’t get me wrong, I think this was a stupid security question, but it’s less stupid than it first sounds because of that.
