B.

Step-by-step explanation:

We have been coordinates of some points on coordinate plane. We are asked to find the reflection image of U across the y-axis.

We know that after reflecting a point across y-axis, the y-coordinate of point remains same, while x-coordinate changes to its opposite sign.

We can see that coordinates of point U are . After the reflection across y-axis the y-coordinate will remain same that is , while x-coordinate will be opposite of that is

Therefore, the coordinates of point U after reflection across y-axis would be and option B is the correct choice.
