Let's take a look at the points of view. The sentence reads, "I went to the coffee shop because you can get really hungry." At the start, we are in the first-person point of view, as the narrator is using the pronoun I. Towards the end of the sentence, we see the word you, which is a pronoun used in the second-person point of view.
Now, lets take a look at the options:
A. Unclear antecedent (This is not unclear, it is only incorrect.)
B. Missing antecedent (Nope, nothing is missing, it is only incorrect.)
C. Shift in point of view (This is our answer! We are changing from the First-person of I into the second-person as you.)
The answer will be C- Shift in point of view.
I hope I've helped! :)
