Herbivorous sauroped dinosaurs could grow more 80 tons, and some researchers have attributed the evolution of to such masive sizes to increased plant production resulting from high levels of atmospheric produce dioxide during the Mesozoic era Li carbon there is no evidence of significant spikes in carbon dioxide levels coinciding with relevant periods in evolution,such as when the first large sauropods appeared, when several sauropod lineages evolution toward gigantism, or when sauropods reached their maximum known sizes,suggesting that __ Which choice most logically completes the text? A)fluctuations in atmospheric carbon dioxide affected different sauropod lineages differently. B) the evolution of larger body sizes in sauropods did not depend on increased atmospheric carbon dioxide. C)atmospheric carbon dioxide was higher when the largest known sauropods lived than it was when the first sauropods appeared. D)sauropods probably would not have evolved to such immense sizes if atmospheric carbon dioxide had been even slightly higher.
