The Figure Included Shows the Body Temperature of Lizards Versus

The figure included shows the body temperature of lizards versus air temperature in two different habitats-open and shaded forest. Which one of the following conclusions is best supported by these data.

A) Lizards are more active in open habitats.
B) Lizards sunbathe more in open habitats.
C) Lizards in shaded forest habitats eat more to maintain their temperature.
D) The body temperature of lizards is more constant in open than in shaded forest habitats.
E) The negative effect of air temperature on body temperature is less in shaded forest habitats because the temperature varies less there.
