    b c and D all are correct only plane is a flat surface on which a straight line joining any two points on it would wholly lie.

    C. A plane contains at least three points that do not lie on the same line. not always true you can have 3 points and all on the same line

    For straight line u need at least 2 points

    and for plane at least 3 points and they should not lie on the same line the last part is important

    There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane. In geometry, a point has no dimension (actual size). Even though we represent a point with a dot, the point has no length, width, or thickness. @popitree

    formally not defined does not mean undefined.. the thing is u can not have ideal plane with zero height.. same with line or point.. u can not draw/create physically the ideal point plane or straightline

    we were arguing unnecessarily.. the correct ans is B
