<span>D. detail that provides information about the wrong subject.
Dangling modifiers happen when it is not clear who is actually doing the action. An example would be, After studying hard for the exam, the exam had arrived. In this sentence it is not clear who studied for the exam. Another example would be: Before leaving for school, the trash need to be emptied. Who is leaving for school? </span>
The correct answer is <span>a. Even the adults were jumping and splashing like children, who usually don't play much.
The clause "who usually don't play much" refers to adults and not children. Here however, due to misplacement, it makes it seem as if the children are the ones who don't play much.</span>
