Triangle abc has been dilated to form triangle def. what is the least amount of information needed to prove the two triangles are similar?

Since triangle ABC has been dilated to form triangle DEF, the least amount of information needed to prove the similarity between the two triangles is 2 pair of corresponding angles. If 2 pairs of angles are corresponding, then the 3rd pair of angles should be corresponding as well. 

The answer is D because you have to divide 812 by 25.3
