What is the document about?
I say D but i’m not 100% sure
I would say the answer is 4
I see only two pronouns here: "you" and "I" - they are both personal pronouns, so the correct answer, whichever of them is underlined, must be "personal".
Some more information that might help:" a reflexive pronoun usually ends with -self, for example: oneself.
A demonstrative pronoun is for example "this"
The answer is D because the author wants the reader to understand the central message of the passage.
