read the following sentence from the passage.
their white skin helps to camouflage them in icy waters like those of the arctic ocean.

b. cold
c. wet

Explanation:

To find the opposite of "icy", we analyze the meaning of "icy" which relates to being very cold. Then we check the options: "warm" is the opposite of cold (and thus opposite of icy), "cold" is similar, "wet" is about moisture, and "water" is a substance. So "warm" is the antonym.

Answer:

A. warm
