Explain What Is Meant by Saying a Vector Field Is $\vec{F}$

Explain what is meant by saying a vector field is conservative.

A) A vector field $\vec{F}$ is called conservative if for any two points P and Q, the line integral
$\int_{C} \vec{F} \cdot d \vec{r}$ has the same value along any path C from P to Q lying in the domain of
$\vec{F}$
B) A vector field $\vec{F}$ is called conservative if for any two points P and Q, the line integral
$\int_{C} \vec{F} \cdot d \vec{r}$ has a different value along any path C from P to Q lying in the domain of
$\vec{F}$
C) A vector field $\vec{F}$ is called conservative if for any two points P and Q, the line integral
$\int_{C} \vec{F} \cdot d \vec{r}$ has the same value along a path C from P to Q lying in the domain of
$\vec{F}$
D) A vector field $\vec{F}$ is called conservative if for two specific points P and Q, the line integral
$\int_{C} \vec{F} \cdot d \vec{r}$ has the same value along any path C from P to Q lying in the domain of
$\vec{F}$
