Geometry

The answer is C.“Line m contains points A and D”.

The Two - Point Postulate states that through any two points, there is exactly one line.

A.The intersection of line m and line n is point D: This represents the Line - Intersection Postulate (if two lines intersect, their intersection is a single point), not the Two - Point Postulate.

B.Line n contains points B and E: Point E is not on line n in the given diagram, so this statement is incorrect.
