(单选题)

Which animal is most in need of protection? ( )

A.Polar bears

B.Ringed seal

C.Narwhals

D.Walruses

参考答案：C

参考解析：

从文章中的第三段Narwhals are at risk because they have more contact with ships in the Northwest Passage, which receives more shipping than the Northern Sea Route. This means they are the most at risk of all the Arctic marine mammals.可知独角鲸之所以处于危险之中，是因为它们与西北航道的船只有更多的接触，而西北航道接收的船只比北海航道多。这意味着它们是所有北极海洋哺乳动物中风险最大的。可以看出Narwhals最需要得到保护。故本题正确答案选C。
