△ABC is reflected to form​​ ​ △A′B′C′ ​.The vertices of △ABC are A(−7, 1) , B(−5, −3) , and C(−3, 2) . The vertices of △A′B′C′ are A′(−7, −1) , B′(−5, 3) , and C′(−3, −2) .Which reflection results in the transformation of ​ △ABC ​​ to ​ △A′B′C′ ​​?A)reflection across the x-axisB) reflection across the y-axisC)reflection across y = xD)reflection across y=−x
