Is the program (e.g Wharton, M&T) you select during applications binding?

If hypothetically, I am accepted into the primary program that I chose, if I attend UPenn do I have to pursue that program, or is it non-binding, meaning I can switch into another program if my preferences change?

definitely you cannot switch to lsm if you get in MT, it’s like u get in CAS but wanna switch to a joint degree program…but still, i’m wondering why not pursue M&T if u can get in
