Which sequence of rigid transformations will respectively produce the images ΔA′B′C′, ΔA′′B′′C′′, and ΔA′′′B′′′C′′′ from the preimage ΔABC?

A. 1. a 90° clockwise rotation of ΔABC about the origin
2. a 180° clockwise rotation of the image about the origin
3. a 270° clockwise rotation of the image about the origin

B. 1. a reflection of ΔABC across the y-axis
2. a reflection of the image across the x-axis
3. a 90° counterclockwise rotation of the image about the origin

C. 1. a reflection of ΔABC across the y-axis
2. a reflection of the image across the x-axis
3. a reflection of the image across the y-axis

D. 1. a reflection of ΔABC across the line y = x
2. a reflection of the image across the x-axis
3. a reflection of the image across the y-axis
