I just started an internship but I found another internship that is more interesting. What are my options?

Dealing with a career is the art of making decisions and the ability to assess options/offers depending on your professionnal and personnal goal's life. Regarding this specific question, it is not possible to terminate an internship just because you found another one that is "more interesting". Terminate an internship is only possible in very specific situations (conflicts, unappropriate missions regarding the contract, harassment,...). The very first option if you are unsatisfied with your current internship is to discuss with your manager and see with him/her whether some arrangements are possible regarding your missions. If things are getting critically wrong, contact the career services. Otherwise, you have to finish your internship. Keep in mind that, as a Business School, our role is also to ensure good relationships on the long run with the companies that are recruiting our students. We are paying a special attention when it comes to terminate an internship.
