The distance of point $$(a, b)$$ to the line $$\alpha x + \beta y + \gamma = 0$$ is

A

$$\begin{vmatrix} \frac{a + b}{\sqrt{\alpha^2 + \beta^2}} \end{vmatrix}$$

B

$$\begin{vmatrix} \frac{\alpha + \beta}{\sqrt{a^2 + b^2}} \end{vmatrix}$$

C

$$\begin{vmatrix} \frac{a \alpha + b \beta + \gamma}{\sqrt{\alpha^2 + \beta^2}} \end{vmatrix}$$

D

$$\begin{vmatrix} \frac{a \alpha + b \beta + \gamma}{\sqrt{a^2 + b^2}} \end{vmatrix}$$
