This question is more complicated than it seems.\n\nFirst of all, both possibilities have been available in English for a very long time.  A couple of hundred years ago, some grammarians looked around and decided that they didn't like that there were two possible ways of saying something, so they decided to make some rules about it.  They decided that, whenever you have an object of the preposition "than", you should put it in nominative case.  That means that, according to many grammar books, the correct answer is "Are you better than I?".  Their reasoning is that the part that comes after "than" is a shortened version of something else, like this:\n"Are you better than I am (good)?"\n\nHowever, to many native speakers, both "I" and "me" are possibilities in this context, so it might only be a concern to you if you are planning on using this sentence with someone who might judge you for it (for example, a boss or a professor).  Anyone else might not even notice.

When you use either/or, or neither/nor, the verb must agree with the subject that is closest to it. B and C as you have typed them here are both correct. Hopefully you will apply that knowledge to your other homework items and do them yourself.

Both....\n\nOne does not need to preclude the other.

Your statement and grammar awnsers that question

the answer is, either something (is) "to be" what it is OR something is (not) "to be" what it is not. either I'm gay or I'm not gay, the choice is mine. either i'am or i am not.i am what i am / i'm not what i'm not.

No. They are two completely different phrases.\n\nYou would say 'Does somebody like this book?' to a group of people. By using 'somebody' you are inferring that there is a group of 'somebody's from which an answer may be selected.\n\n'Does anybody like this book' is asking a question about people in general. Is there anyone out there who likes this book? Anybody is not a definite statement; it is used to refer to a large, uncertain group, not a certain group as somebody is.\n\nFor example, if you were speaking to someone about a party, and you said 'Did you hear that so-and-so was sick?' They could respond 'Yeah, somebody told me that.' The 'somebody' can be attributed to an unknown person in a specific group. You could not use 'anybody' in that situation.\n\nSometimes, the two are interchangable, when the group is particularly large. 'Can somebody hear me?' is referring to a person who would be within range. 'Can anybody hear me?' would be a general request for help. But just because either word can be used doesn't mean they are always interchangable.
