Answer:
A and C
Explanation:
This question asks about the internal citations. Remember:
- in-text citations occur in parentheses
- the parenthetical expression should come before the period ending the sentence
- the in-text citation should also be outside the quotation marks
- there are different formats of in-text citations; they can have simply the page number (like 23 in this case) or they can have the last name of the author, followed by the page number the information is found on (like Keller 23)
Looking at the answer choices, we see that B doesn't work because (23) is inside the quotations, which is not allowed. We also see that D doesn't work because (23) is outside the period, which is again not allowed. However, A works because it's in the right place, and C works because it's exactly like A, just with "Keller".
Thus, the answers are A and C.
