( $h$ is angular momentum, $\mu$ is gravitational parameter, $e$ is eccentricity, $r$ is radial distance from the planet center, $\theta$, is angle between vectors $\vec{e}$ and $\vec{r}$. (A) $r=\frac{\left(h^{2} / \mu\right)}{1-e \cos \theta}$ (B) $r=\frac{\left(h^{2} / \mu\right)}{e-\cos \theta}$ (C) $r=\frac{\left(h^{2} / \mu\right)}{1+e \cos \theta}$ (D) $r=\frac{\left(h^{2} / \mu\right)}{e+\cos \theta}$
