Answer:
Option B
Explanation:
Answer A is incorrect as the data is not analyzing how many fish each lake has, but rather the pelvic score of the fish. Answer C is incorrect as the graph shows that the fish in Frog Lake are complete, and that there are 0 fish that have reduced or absent pelvic scores, therefore the fish don't have varying pelvic structures. Answer D is incorrect because the data is not analyzing the size of the fish and again is only analyzing the pelvic score of the fish. This being said by process of elimination the answer would be option B, as the fish in Bear Paw Lack lack complete pelvic spines but rather have reduced or absent pelvic spines.
