Accepted Answer

Dear XXXXXXXXXXXX,

Great question. Here's how I'd answer it.

A plane is defined by three points. Since two coplanar lines fall in the same plane (by definition), then we can easily find three points on those lines. So I would say that the solution is C Definition of a plane       

Let me know if you have questions about this. I'm happy to clarify any details.
