A team of researchers has developed a poison that has proven effective against lamprey larvae in freshwater cultures. The poison is ingested and causes paralysis by detaching segmental muscles from the skeletal structures. The team wants to test the poison's effectiveness in streams flowing into Lake Michigan, but critics worry about potential effects on lancelets, which are similar to lampreys in many ways. Which of the following arguments best addresses the critics' concerns?
A) Lamprey larvae and lancelets have very different feeding mechanisms.
B) Lancelets do not have segmental muscles.
C) Lancelets live only in saltwater environments.
D) Lancelets and lamprey larvae eat different kinds of food.
