Kudos to you for knowing what career path you want to take!
There are a couple of ways of doing that. First, you can talk to professionals who are already successfully established in the career field that you want to join, and find out what are the typical college majors for that field. If there are a few, then you can ask about the pros and cons of each, assuming that you'd be OK with either major.
Second, you can talk to your teachers who are teaching classes in that major, and ask whether they thought the major could help support your entry into that particular career path. Most Professors teaching a subject in college will have taken courses with many people who went into careers outside of Academia, and they would probably have a pretty good idea of where their old friends ended up in terms of their career.
Third, if you at least have the names of a few professionals already established in the career that you want, then you should be able to look them up on LinkedIn and perhaps their background will tell you what they majored in.
Hope this helps, and good luck!
