C. Assume that the two points lie on different lines. 


A.
 
A, C, B
 

B.
 
B, C, A

Thanks!

Wait actually I made a mistake, its D

kendricklamar2014 · Answer

Explanation: You start by assuming that the two points lie on different lines (C)

this leads you to the fact that the two points aren't collinear (B)

and A is an odd wording...I think it meant to say "points" instead of lines

anonymous · Answer

That actually makes more sense, if by definition two lines or points aren't collinear then A should be the last one. That you for taking time and helping me, I appreciate it.
