Answer:

C. 12 square units

Step-by-step explanation:

Length of side E'F' = EF*scale factor = 3*2 = 6 units

Length of side D'E' = DE*scale factor = 1*2 = 2 units

Area of rectangle = length * width

Therefore, area of rectangle D’E’F’G’ = length of side E'F' * length of side D'E' = 6*2

area of rectangle D’E’F’G’ = 12 square units
