What would I put as my vocal range on an audition form?

So my theatre, on their audition forms, have a musical theatre spot. On this spot, you must list your vocal range/voice type. I’m auditioning for my first musical in a day, and I have no idea how to figure it out or what I should put. I know I’m not bass or counter tenor lol. I’m a girl that is in her teens, ig this helps any. my brother says I’m a tenor but idk at the moment.
