What is the domain and the vertical asymptote (VA), respectively, of $$f(x) = \log_{5}(x-4)-4, x > 0$$?

A

$$\left\{x\mid x = 0\right\}, VA \Rightarrow x = 0$$

B

$$\left\{x\mid x > 4\right\}, VA \Rightarrow x = 4$$

C

$$\left\{x\mid x = 4\right\}, VA \Rightarrow x = 4$$

D

$$\left\{x\mid x > 0\right\}, VA \Rightarrow x = 0$$
