Answer:
A. Enlargement
Step-by-step explanation:
We are given that,
Quadrilateral ABCD is dilated by a scale factor of [tex]2\frac{1}{2}=\frac{5}{2}[/tex].
Now, we know that,
Dilation changes the size of the figure by the scale factor 'k'.
If 'k' > 1, then the dilated figure is enlarged in size.
If 0 < 'k' < 1, then the dilated figure is reduced in size.
Since, the given scale factor is [tex]\frac{5}{2}=2.5>1[/tex].
So, the quadrilateral ABCD is enlarged in size.
Hence, option A is correct.
