Let $f(x) = a_{0}x^{n} + a_{1}x^{n-1} + a_{2}x^{n-2} + \ldots + a_{n-1}x + a_{n}$,where $a_{0}, a_{1}, a_{2}, \ldots, a_{n}$ are constants. If $f(x)$ is divided by $ax - b$,then the remainder is:

• A
  $f\left(\frac{b}{a}\right)$
• B
  $f\left(-\frac{b}{a}\right)$
• C
  $f\left(\frac{a}{b}\right)$
• D
  $f\left(-\frac{a}{b}\right)$
