D). The problem-solution structure explains why students are late to science class in order to advise that they be let out of swimming class earlier.
Explanation:
The organizational structure is characterized as the pattern, sequence, or arrangement in which the content or text is presented by the author. It allows the readers to understand the message conveyed by the author more conveniently.
In the given paragraph, the use of 'problem-solution' structure elaborates the reason due to which the students get late for the science class and suggests that they must be released earlier from the swimming class to ensure that the students reach science class on time. The author <u>first discusses the problem('Students do not have enough time to get to class before the bell rings') followed by the causes('both the places are two farthest points and they have to drop off their heavy, wet swim bags, before the science class' and then stating its solution(that they must be released earlier) allows a better comprehension</u> for the readers. Hence, <u>option D</u> is the correct answer.
