ANSWER

Third option

Step-by-step explanation

We want to identify the graph that correctly describes the points.

The first quadrant on a coordinate grid is the quadrant located in the top right corner of the coordinate grid.

Also, we have that point B is located at (-1/2, 1) and C is a reflection of point B across the y-axis.

When a point is reflected across the y-axis, it changes as follows:


(x,y)\to(-x,y)

This implies that point C is located at:


((1)/(2),1)

Therefore, the graph that correctly describes the points is the third option.
