Which of the following about the copperhead snake is true?

a.

The copperhead snake is one of six venomous species in North America.

b.

Copperhead snakes average 4.5 feet in length.

c.

Copperhead snakes are not camouflaged.

d.

Copperhead snakes detect heat given off by potential prey.

B is wrong, since the average length of a copperhead is 30 inches (76cm) and so is C, because copperheads blend in with nearly anything. If there's only one true statement, it would be A - the copperhead snake is one of six venomous species in North America because a small bite from one can be fatal. A is your answer.
