Which sequence of transformations will change figure pqrs to figure p′q′r′s′?

I think it is the third one. If it’s not the third one then it’s the first one.

The answer is a counterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axis.  

Step-by-step explanation: For every square, it is one 90 degree angle, or rotation.  If the figure PQRS is rotated to the left square, that would be considered a 90 degree angle.  If you do 180 degrees, it would be on the lower left.  A 270 degree angle and it would be with P'Q'R'S'.  A whole 360 degree angle would be right back where it started, or where PQRS is.  So if a 180 degree rotation is made, the last step would be to reflect over the y axis.  The y axis is the vertical, or upright line.  

answer: the answer is b. i think hope i got it correct
