PLSS ANSWER QUICKLY 69 POINTS △ABC is reflected to form​​ ​△A′B′C′​.

The vertices of △ABC are A(3, 1), B(1, 5), and C(6, 9).

The vertices of △A′B′C′ are A′(−1, −3), B′(−5, −1), and C′(−9, −6).

Which reflection results in the transformation of ​△ABC​​ to ​△A′B′C′​​?

A: reflection across the x-axis

B: reflection across the y-axis

C: reflection across y = x

D: reflection across y=−x
