Colleges should have no interest in what your parents did, as it isn't necessarily applicable to the path you want to follow. Your employment history is also irrelevant because, again, it's your path. What makes A wrong is that they should have very little interest in your personal life and do not need to know any of your private information (e.g. credit cards, relationships, etcetera). The correct answer is C because you are going to college to pursue a certain career and they must know what it is you want (or plan) to do.
