Answer: The correct option is A.

Explanation:

From the given figure it is noticed that each box in the graph represents the length of 2 units. The coordinates of point A,B and C are (-1,1),(-3,3) and  (-2,4) respectively.

If a point reflects over the y-axis then,

(x,y)\rightarrow(-x,y)

So after reflecting coordinates of point C become,

(-2,4)\rightarrow(2,4)

If a point translated by (a,b), then

(x,y)\rightarrow(x+a,y+b)

So, after reflection over y-axis followed by translation by (2,-2), the coordinate of C are,

(2,4)\rightarrow(2+2,4-2)\\(2,4)\rightarrow(4,2)

Similarly the image of point A and B are (3,-1) and (5,1) respectively.

The image of C after reflection over y-axis followed by translation by (2,-2) is (4,2), which is shown in only graph A, Therefore A is the correct option.
