Explanation:

As per the passage we know that Penguins maintain their plumage temperature lower than the outer atmosphere to get body heat. Now the warmer air refers to the atmospheric air being slightly higher than the plumage, and the colder temperature refers to the colder air in the atmosphere once the heat is transferred to the penguin’s body. This can be inferred only through Option 1, rest of the options are incorrect.

Hence, the correct answer is option 1.
