Which statement must be true to prove that segment DE is parallel to segment CA?
1 : DC = 5 : EA
4 : DC = 3 : EA
1 : EA = 5 : DC
4 : EA = 3 : DC
I don't get this.

you need to find a ratio that matches the given options, the ratio willbe help you identify the condition why the lines may be parallel
also if you should know about similarity of triangles, thats where these relations come from
