The statement that uses the correct MLA in-text citation is B: Lenore Westerberg, author of the book Monkey in the Middle, says that young children who participate in sports are more likely to understand the value of teamwork (25).
The name of the author is already included in the quoatation, so it is not necessary to repeat it again as in D. A is vague because the name of the author is not mentioned at all. What does the number 25 referred to then ? Finally, in C the page number is not included.
It's been a while since i last did a test on it
i say it was probably B
