Answer:
I love living in the city, there are so many things to do. (D)
Explanation:
I say so because in answer choice A, nothing is wrong with the sentence, therefore the semicolon does not need to be there.
B is also incorrect because there isn't a person for there to be dialog.
C is also not the answer because no pause is needed between "city" and "there."
With this conclusion, I say D is the answer because without the comma, it would be a run-on sentence. By adding the comma, and the conjunction, you therefore make it into a compound sentence.
I'm stupid, but I hope I did some good! :)
