Find the Domain of the Rational Expression $f ( x ) = \frac { 1 - 2 x } { x ^ { 3 } - 2 x ^ { 2 } - 3 x }$

Find the domain of the rational expression.
- $f ( x ) = \frac { 1 - 2 x } { x ^ { 3 } - 2 x ^ { 2 } - 3 x }$

A) $\{ x \mid x$ is a real number and $x \neq - 3 , x \neq - 1 , x \neq 0 \}$
B) $\left\{ x \mid x \right.$ is a real number and $\left. x \neq 3 , x \neq - 1 , x \neq \frac { 1 } { 2 } , x \neq 0 \right\}$
C) $\left\{ x \mid x \right.$ is a real number and $\left. x \neq 3 , x \neq - 1 , x \neq \frac { 1 } { 2 } \right\}$
D) $\{ x \mid x$ is a real number and $x \neq 3 , x \neq - 1 , x \neq 0 \}$
