HELP LIKE RN PLEASE! The author of Passage 1 makes the claim that animal testing is necessary. Which ONE sentence below from Passage 2 BEST refutes this claim?

A“Microdosing means human subjects are given doses that are too small to cause a full-scale adverse reaction, and their blood is then simply analyzed for data.”
B“For example, a DNA synthesis test on an animal costs over $30,000, while the same test on human cells in a beaker costs about $10,000.”
C“Likewise, medications successfully tested on animals could kill humans immediately when going to market.”
D“For perspective, over 25 million animals are completely unprotected from abuse and mistreatment every year.”
