D: They already know your name. It is in your heading. Also, I doubt the person reading it wouldn't care about what your name is. (Sorry if that came out mean, I didn't mean it.... I am really A nice person!)
C: Don't just throw in reasons in their face without them knowing what you are talking about.
A: Personally I wouldn't do that, First you should at least say some interesting facts to get the reader hooked on.
Okay so B and C are both good ones. But A and D are very off so it’s either one of those. So since this is a thesis essay you 100% do not want to put “hello my name is...” it is just not a very formal way to start any essay, it Is just not appropriate. But A you aren’t supposed to have your opinion in a thesis essay but if you are just stating your view point it’s ok but try not to put your opinion i there.
