I think 6, if we join both lines then point W and V will not be on the line rest all six can be on same line

B. Two lines have 3 points on each. In order to complete the triangle 4th point has to be on another line.

I guess you are confusing lines with line segments.
Whereas line segments can be joined together, a line extends infinitely in both directions.
So joining both lines makes no sense.

Each line has 3 points already. To form the Triangle it has to have one more point on the other line , making 4 point on each line.
