The Gila monster, a poisonous lizard, spends most of its life under rocks or burrowed in the ground. Which hypothesis most likely explains the Gila monster’s behavior?
a. The Gila monster has very few defenses and must hide from predators.
b. The Gila monster must hide underground or under rocks to ambush passing
prey.
c. The Gila monster feeds exclusively on small insects that live in the ground or
under rocks.
d. The Gila monster can only control its body temperature during hot desert days by
seeking cooler places.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
