Answer:
A. Latham points out that the value of French art has steadily increased for the past three decades, resulting in higher demand from collectors (52).
Step-by-step explanation:
When it comes to in-text citations, MLA has some basic rules to follow:
1) in-text citation is written in parentheses at the end of cited or paraphrased sentence
2) it must contain author's name and page number
3) if the author is mentioned in the sentence, then in-text citation only contains page number
4) page number should always be written in parentheses and not in the sentence itself
5) in-text citation must correspond to the information provided in the Works Cited page
Now, we see that answer B. lacks page number, answer C. lacks any in-text citation and answer D. has page number written in the sentence.
hope this helps
