Answer 1

So lets define colinear and coplaner.  Colinear basically means 2 or more points that are on the same line.  Coplaner means 2 lines (or more) that are the same plane.  For the first answer choice, point M is not on the same line as the others, so that is incorrect.  For the second choice  all the points are on the same line, so that is one answer.  For the third answer choice all the points on the lines are on the back right plane, so that is your second answer.  The fourth answer choice is incorrect because point L is above the plane of which the others are located.
