Answer:
D
Step-by-step explanation:
Given a square with vertices at points (2,1), (1,2), (2,3) and (3,2).
Consider option A.
1st transformation  will map vertices of the square into points
 will map vertices of the square into points 
2nd transformation = reflection over y = 1 has the rule (x,2-y). So,
These points are exactly the vertices of the initial square.
Consider option B.
1st transformation  will map vertices of the square into points
 will map vertices of the square into points 
2nd transformation = reflection over x = 3 has the rule (6-x,y). So,
These points are exactly the vertices of the initial square.
Consider option C.
1st transformation  will map vertices of the square into points
 will map vertices of the square into points 
2nd transformation = reflection over y = -x + 7 will map vertices into points 
These points are exactly the vertices of the initial square.
Consider option D.
1st transformation  will map vertices of the square into points
 will map vertices of the square into points 
2nd transformation = reflection over y = -x + 2 will map vertices into points 
These points are not the vertices of the initial square.
