We have to remember that two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio (in other words, if they are proportional).
Also, regular polygons with the same number of sides are always similar, we can determine that pentagon ABCDE is similar to pentagon FGHIJ.
In that sense, we are left with options A. and D., but A. says that units are added to the figure fgde and that is false according to the statement.
Thus, The correct answer is D.
