The Sound of Music audition help?

I am auditioning for a community production of The Sound of Music on May 15. I am auditioning for Leisl. I am fifteen and will be sixteen next February. I have a few songs picked out, but I don't know which one to pick. I have chosen Home from Beauty and the Beast, Someone Like You from Jekyll and Hyde and A New Life from Jekyll and Hyde. I was trying to stay in a certain range because Sixteen Going on Seventeen goes up to a high D sharp I'm pretty sure. All of these songs that I have chosen go up to a high D sharp or higher. Can you give me suggestions on which song I should do?
