Answer: The correct option is (A) reduction.

Step-by-step explanation: Given that the quadrilateral A'B'C'D' is a dilation of the quadrilateral ABCD.

As shown in the given figure, the lengths of the sides of quadrilateral ABCD are as follows:

AB = 5 units, BC = 4 units, CD = 10 units and DA = 6 units.

And, the lengths of the sides of quadrilateral A'B'C'D' are as follows:


A'B'=1(1)/(4)=(5)/(4)~\textup{units},~~B'C'=1~\textup{units},~~C'D'=2(1)/(2)=(5)/(2)~\textup{units},\\\\D'A'=1(1)/(2)=(3)/(2)~\textup{units}.

We know that the dilation will be an enlargement if the scale factor is greater than 1 and it will be a reduction if the scale factor is less than 1.

Now, the scale factor is given by


S=\frac{\textup{length of a side of the dilated figure}}{\textup{length of the corresponding side of the original figure}}\\\\\\\Rightarrow S=(A'B')/(AB)=((5)/(4))/(5)=(5)/(4*5)=(1)/(4)<1.

Since the scale factor is less than 1, so the dilation will be a reduction.
