Answer:
D
Explanation:
It is D because there are only 3 sides given. I understand where you were going with B, but there is no angle given, (and you cannot prove one either), so the answer is simply D.
A - There is no angle, triangle does not matter
B - There is no angle, triangle is correct
C - It is similar, they have the same scale factor
D - There are 3 sides, and the triangle is correct
