-In the Study Shown in the Figure, Male African Clawed

-In the study shown in the figure, male African clawed frogs were treated with atrazine, which is the most commonly applied herbicide (weed-killer) in the world. These frogs were compared to untreated frogs. Treated and untreated frogs were presented with a female and the number of successful matings of each was recorded. What can you conclude from the data shown?

A) Atrazine causes feminization of male frogs.
B) The level of testosterone is lower in frogs treated with atrazine than in those of the untreated group.
C) Frogs cannot mate successfully if their testosterone is too high.
D) Atrazine prevents successful mating in all African clawed frogs.
