Answer:
A and D
Step-by-step explanation:
ΔACD is 3 times the size of ΔABE, so the dilation uses a scale factor of 3. That only leaves choices A, D, and E.
Dilation about point A leaves point A in the same place, so choice E can be eliminated on that basis. (There is only one point A, and not a translated version, consistent with choice A.)
Point C in the larger triangle corresponds to point B in the smaller triangle, and is 4 units down from it. Hence the description of D makes sense.
___
We hope you can see that choosing correct answers in multiple-choice questions is as much about consistency and reasonableness as it is about knowing how to work the problem. You do have to understand what the problem is asking and what the answers are saying about it.
