A
Chinstrap
B
Emperor
C

D

Correct answer: A
Explanation
Choice A is correct. It is given that there are 180 female penguins in the exhibit. Therefore, of the female penguins is penguins. According to the table, there are 59 female chinstrap penguins, 27 female emperor penguins, 54 female gentoo penguins, and 40 female macaroni penguins. So the female chinstrap penguin population is the closest to 60, or of the total female population in the exhibit.
Choices B, C, and D are incorrect and may result from reading data from the table incorrectly. Since the total female penguin population is 180, of the total female penguin population is 60. The numbers of female emperor (27), female gentoo (54), and female macaroni (40) penguins are not as close to 60 as the number of female chinstrap penguins (59).
