The function $f(x) = |x| + \frac{|x|}{x}$ is

  • A
    continuous at the origin
  • B
    discontinuous at the origin because $|x|$ is discontinuous there
  • C
    discontinuous at the origin because $\frac{|x|}{x}$ is discontinuous there
  • D
    discontinuous at the origin because both $|x|$ and $\frac{|x|}{x}$ are discontinuous
