When reflection is done across the y coordinate, the point on the y axis is left unchanged while the point on the x axis is mirrored(the sign is reversed)

For the point B on the graph, the original coordinate is (- 2, -1)

Since it is reflected across the y axis, only the sign on the x coordinate would the reversed. Therefore,

the coordinate of B prime is (2, -1)

option D is correct
