Identify geometric notations

Using the Geometric Notation knowledge point
\[

$$\begin{aligned} &\overleftarrow{CD} \quad \text{represents a ray extending infinitely to the left through } C \text{ and } D.\\ &\overleftrightarrow{EF} \quad \text{represents a line extending infinitely in both directions through } E \text{ and } F.\\ &\overline{GH} \quad \text{represents a line segment with endpoints } G \text{ and } H.\\ &\overrightarrow{JK} \quad \text{represents a ray extending infinitely to the right through } J \text{ and } K. \end{aligned}$$

\]

Select the correct option

Using the Geometric Notation knowledge point
\[
\text{The symbol for a line segment is a simple bar over the letters: } \overline{GH}.
\]
