A) I only
B) II only
C) I and II only
D) All statements are true.

Because f(x) = f(-x) (f is an even function), I is automatically true, and III is false. II depends on the domain of the function, and whether
it is continuous over that domain. In general, it is NOT true. (Take f%28x%29+=+10+%2B+1%2Fx%5E2, which is continuous over its domain R\{0}, but has the
vertical asymptote x = 0.)
