Question

which is a sketch of $overrightarrow{ab}$ and $overleftrightarrow{ac}$?

Explanation:

Step1: Understand vector - ray notation

$\overrightarrow{AB}$ is a ray starting at point $A$ and going towards point $B$. $\overleftrightarrow{AC}$ is a line passing through points $A$ and $C$.

Step2: Analyze each option

Check the starting - points and directions of the rays and lines in each option.

Answer:

The option where there is a ray starting at $A$ and going towards $B$ and a line passing through $A$ and $C$ is the correct one. Without labeled options, it's not possible to give a specific letter - choice answer, but the correct sketch should have a ray with an arrowhead starting at $A$ and pointing towards $B$ and a two - way arrowed line passing through $A$ and $C$.
