Rattlesnakes, typically found in the American Southwest, are known to shed their skin during the fall months. Rattlesnakes generally forage for food in open desert areas during the spring and summer months; beginning every autumn, however, most rattlesnakes remain hidden, hunting among rocks and brush. The seasonal variations in rattlesnakes' patterns of movement can probably be explained by the rattlesnakes' vulnerability to predators.
Which of the following, if true, provides the strongest support for the explanation offered?
(A) It is in the spring and summer months that brush and rocks offer rattlesnakes the most protection from predators.
(B) The number of predators hunting any given rattlesnake varies from one year to the next.
(C) Rattlesnakes subsist primarily on small insects that are plentiful only during the summer.
(D) When rattlesnakes are shedding their skin, they appear larger and more visible to predatory birds.
(E) Brush and rocks are often the only source of warmth for animals in the freezing desert nights.
