A and D!
JKE and KEJ line up and are in the correct position and order to form the triangle listed by themselves. The other ones will not form even the same shape!
The reason why the other ones aren't elgible: EJR, KE and JE just form a line, and JAOE forms an uneven trapezoidal shape (forgot what it was called)
So that would leave JKE and KEJ, which are the only ones that line up.
c) Δ JKE
F) Δ KEJ
Triangle should be named by the vertexes.
