This Figure Shows the Basal and Fever Temperatures for Various

This figure shows the basal and fever temperatures for various vertebrates. If fever conferred only benefits, and had no costs, how might you expect this graph to differ?

A) Basal temperatures would be more like fever temperatures.
B) Fever temperatures would be lower than basal temperatures.
C) Ectotherms would have higher basal temperatures than endotherms.
D) Basal temperatures would be even lower than fever temperatures.
